1. Diagnostics First: Sample Analysis

Every transformer repair begins with thorough diagnostics – the foundation for all subsequent maintenance activities. Diagnostics allow us to assess the true technical condition of the equipment and detect problems early, before they escalate into costly failures. One of the most critical steps in this process is taking transformer oil samples and performing a detailed analysis. Why is oil so important? It plays a vital role in insulating and cooling the transformer, while also serving as an early warning system. How do we do it?

We perform Dissolved Gas Analysis (DGA) – one of the most effective methods for diagnosing transformer issues. This technique helps us identify problems such as:

• Micro-cracks in the insulation, which over time can lead to short circuits,

• Overheating of components, often a sign of overloading,

• Partial discharges, an early indicator of electrical failures.

You can think of it as a blood test for a transformer – even the slightest deviations from the norm signal issues that need immediate attention. Regular oil analyses can reduce the risk of serious failures by up to 40%.

Contaminants in the oil, such as moisture, aging byproducts, or gases generated by overheating, can significantly impair the effectiveness of insulation and cooling. Ignoring these problems for too long can result in irreversible damage to internal components, such as windings or the transformer core. With DGA analysis, we can precisely pinpoint the source of the problem and propose effective solutions before a failure occurs.

Where does diagnostics begin?

The diagnostic process starts with the collection of a transformer oil sample under controlled conditions. The sample is then sent to our laboratory, where it undergoes advanced testing. The analysis includes:

• Dissolved Gas Analysis (DGA) – this test identifies which chemical reactions are occurring inside the transformer.

• Moisture content testing – moisture in the oil reduces insulation efficiency and can lead to corrosion of metal components.

• Analysis of physicochemical properties – we check parameters such as viscosity, surface tension, and acidity of the oil.

Case Study #1

In one of our projects, diagnostics revealed high concentrations of hydrogen and carbon monoxide in the oil, indicating the early stages of winding overheating. Thanks to swift intervention – including oil purification and the replacement of damaged components – we prevented a potential failure that could have caused production downtime valued at 117,670 EUR per day!

As a result, the transformer's lifespan was extended by 8 years, and the client avoided the costly replacement of the equipment.

Regular transformer oil diagnostics is not just a preventive measure – it’s an investment in the safety and reliability of your energy infrastructure. With these practices, you can be confident that your transformer operates efficiently and safely, even under the most demanding conditions.

2. Oil Regeneration: Revitalizing Your Transformer’s Energy

Transformer oil is more than just a liquid – it’s a critical component responsible for both cooling and electrical insulation. Its properties directly impact the efficiency and safety of the transformer’s operation. Over time, however, the oil degrades – moisture, acids, and aging byproducts accumulate, reducing its insulating and cooling capabilities. Oil degradation not only increases the risk of overheating but also creates conditions conducive to short circuits, potentially leading to costly failures.

Imagine transformer oil as the bloodstream of your transformer. If it becomes contaminated, the entire “machine” begins to function less efficiently, and the risk of damage increases dramatically. Regular oil regeneration helps remove harmful contaminants, such as:

• Acids – oxidation byproducts that can cause corrosion of internal components,

• Moisture – one of the primary factors in insulation degradation,

• Solid particles – deposits that can clog the cooling system and increase power losses.

By regenerating the oil, the transformer regains its original insulating and cooling properties, which can extend its lifespan by several years.

How do we perform oil regeneration?

The oil regeneration process is a comprehensive operation that includes:

• Mechanical filtration – we remove solid particles and deposits that could negatively impact the cooling system.

• Vacuum dehydration – we reduce the moisture content in the oil, significantly improving its insulating properties.

• Chemical adsorption – using specialized sorbents, we eliminate oxidation byproducts and other harmful contaminants.

• Quality control – every regeneration process concludes with laboratory tests that confirm the oil meets current standards.

If regeneration is insufficient, we replace the oil with new oil that meets the highest industry standards, ensuring the equipment's reliability and safety.

Case Study #2

In one Polish factory struggling with transformer overheating, we conducted an oil regeneration process. Analysis revealed high levels of moisture and acids, which reduced cooling efficiency. Through our regeneration process, the operating temperature of the transformer was reduced by 12°C. The result? The transformer gained an additional 7 years of fault-free operation, and the factory owner avoided a costly equipment replacement, saving hundreds of thousands of EUR.

Oil regeneration is not only a way to extend the life of your transformer but also an investment in the safety and efficiency of your energy infrastructure. By regularly refreshing the oil, you minimize the risk of failures and enhance the reliability of your power system. This is a proactive approach that delivers tangible savings and ensures your transformer operates flawlessly for years to come.

3. Diagnostic Measurements: Data That Ensures Safety

A transformer is a device whose reliability relies on the precise functioning of every component. Diagnostic measurements are like a thorough health check – they help assess the current technical condition of the transformer and identify potential problems before they escalate into major failures. Without this data, any repair or modernization efforts would carry a high risk of error. Statistics show that regular measurements reduce the risk of failures by an average of 30%, translating into significant savings in terms of downtime and repair costs.

Diagnostic measurements involve a series of tests that examine critical aspects of the transformer’s performance. The most important ones include:

• Insulation resistance testing – verifies whether the winding insulation is effective enough to prevent current flow between elements with different potentials,

• Dielectric strength tests – assess whether the transformer can safely operate under full load conditions,

• Power loss analysis – identifies potential issues related to overheating or aging components.

Why do we do this? During its operation, a transformer is exposed to many factors, such as overloads, vibrations, and changing environmental conditions. Over time, these stresses can cause micro-damages, which – if not detected – may lead to costly failures or complete loss of the equipment.

- how do we conduct diagnostic measurements?

The diagnostic measurement process at Energeks is meticulously planned and based on the latest technologies. We perform:

• Insulation resistance testing – using specialized equipment, we measure whether the winding insulation continues to fulfill its role. A drop in resistance may indicate insulation degradation.

• Dielectric strength tests – the transformer is subjected to high voltage to check if it can withstand such loads under normal operating conditions.

• Power loss analysis – we measure how much energy the transformer loses during operation, allowing us to assess its efficiency and the condition of components such as windings or the core.

• Power factor (PF) measurement – this test evaluates insulation quality and can reveal moisture or other contaminants that weaken its properties.

Each measurement is thoroughly documented, and the results are analyzed in our laboratory, enabling us to precisely determine the necessary actions.

Case Study #3

In one of our projects, we conducted comprehensive diagnostic measurements on a transformer operating in an industrial facility. The dielectric strength test revealed signs of insulation degradation, while the power loss analysis highlighted inefficiencies in the core’s performance.

Based on this data, we recommended replacing parts of the insulation and regenerating the oil, restoring the transformer to full functionality. The client avoided a costly failure that could have resulted in factory downtime, with daily revenues of €119,565.

Diagnostic measurements are not just technical procedures – they are the key to operational safety and the longevity of a transformer. They allow us to proactively plan necessary repairs or modernizations, avoiding costly failures and downtime.

Regular measurements are an investment that pays off in reliability and safety for your energy infrastructure.

4. Bushing Repair and Connection Modernization

Transformer bushings are critical components that connect the transformer windings to the power grid while providing electrical insulation. Despite their crucial role, bushings are one of the most common sources of transformer failures. Why? Over time, they can suffer from mechanical damage, environmental exposure (moisture, contaminants), or degradation of insulation materials. These issues can lead to oil leaks, weakened insulation, and even dangerous short circuits that threaten both the transformer and the grid's safety.

Damaged bushings are like a leaking bridge in the power network – even the smallest defect can eventually turn into a major problem. Oil leaks not only waste a vital cooling and insulating medium but also increase the risk of failure. Moreover, unaddressed bushing problems can compromise insulation, leading to overloads and short circuits.

Modernizing bushings and connections is not just a way to restore the full functionality of a transformer – it is also an opportunity to adapt the device to new grid requirements. Modern technical standards and energy needs are constantly evolving, making modernization a key step in enhancing the transformer's efficiency and compliance with current norms.

- how do we modernize bushings and connections?

At Energeks, we offer comprehensive services for bushing repair and modernization, which include:

• Bushing inspection – we thoroughly examine insulation, tightness, and oil levels in the bushings to identify potential issues.

• Damage repair – we eliminate oil leaks, regenerate insulation, or replace damaged components.

• Replacement with modern bushings – we install new bushings compliant with current standards, offering greater durability and efficiency.

• Adjustment of connection groups – we modify transformer winding connection groups to adapt them to new grid requirements or specific client needs.

Every step of the process is carried out with attention to detail and utilizing the latest technologies to achieve optimal results.

Case Study #4

In one of our projects for a large industrial facility, we diagnosed bushings with significantly reduced insulation and minor leaks. The work involved replacing the damaged bushings with modern models and adjusting the connection groups, allowing the transformer to operate under more demanding load conditions. The result? The transformer's efficiency increased by 18%, and the facility avoided downtimes that could have cost hundreds of thousands of euros.

Modernizing bushings and connections is an investment that brings measurable benefits:

• Improved transformer performance – the device operates more efficiently, which can increase its capacity by up to 20%.

• Reduced risk of failure – new, standards-compliant bushings are more resistant to environmental factors and stress.

• Adaptation to new grid requirements – adjusting connection groups allows for flexible adaptation of the transformer to new operating conditions.

Bushing repair and modernization is not just about fixing problems – it’s a step into the future, ensuring your transformer operates reliably even under the most demanding conditions. Regular inspection and modernization are key to stability and safety throughout the power grid.

5. Sampling and Insulation Analysis: Guarantee of Durability

The insulation of transformer windings is the foundation of the entire device’s safety. Its primary task is to prevent the flow of current between different parts of the winding operating at various potentials. The strength of the insulation determines the stability, efficiency, and safety of the transformer. Over time, under the influence of high temperatures, moisture, or material aging, the insulating properties can deteriorate significantly. Regular sampling and insulation analysis help prevent these issues and maintain the transformer in optimal technical condition.

Insulation acts as the transformer’s protective shield – without it, the windings would be exposed to overvoltages and short circuits, which could lead to failures or even complete destruction of the device. Moisture, chemical contaminants, or overheating can gradually erode the insulation structure, reducing its effectiveness. This phenomenon is particularly dangerous because insulation damage often develops slowly, remaining undetected until a failure occurs.

According to statistics from the International Energy Council, insulation degradation is responsible for approximately 30% of all transformer failures. Therefore, regular testing and analysis of the insulation condition are crucial to ensuring the reliability of the device and the safety of the entire power system.

- how do we perform insulation sampling and analysis?

The insulation sampling and analysis process at Energeks is a meticulously planned operation that includes:

• Insulation sample collection – we use precise methods to evaluate the dielectric properties of insulating materials.

• Moisture testing – moisture is one of the greatest enemies of insulation, so we carefully measure its content and determine whether it is within acceptable limits.

• Dielectric strength tests – we assess the insulation’s ability to withstand high voltages, which allows us to predict its behavior under real operating conditions.

• Insulation aging analysis – we examine the extent to which insulating materials have degraded due to the transformer’s long-term operation.

Based on the results of the analysis, we can determine whether the insulation requires regeneration, replacement, or the application of modern technologies to restore its original properties.

Case Study #5

In one of our projects, we examined the insulation of a transformer that had been operating for several years under high-humidity conditions. The analysis revealed a significant moisture level, reducing dielectric strength by 20%. We implemented a process of insulation drying and dielectric material regeneration, which restored its original properties. The result? The transformer regained full functionality, and the client avoided a failure that could have resulted in production downtime worth tens of millions of euros.

Regular insulation sampling and analysis can reduce the risk of insulation failure by as much as 50%. This is a critical action that minimizes downtime and repair costs while ensuring the stability of the transformer’s operation. Insulation analysis is not just a diagnostic procedure – it’s an investment in the safety and reliability of your energy infrastructure.

With regular testing, you can be confident that your transformer operates efficiently and safely, even under the most demanding conditions.

6. Cooling System Modernization: More Than a New Lease on Life

The transformer cooling system is one of the most critical components responsible for its stable and safe operation. Overheating is one of the greatest threats to transformers – it can lead to insulation degradation, reduced efficiency, or even the complete failure of the device. Cooling system modernization is a key step in the transformer revitalization process, allowing it to be adapted to new, more demanding working conditions and significantly extending its lifespan.

Under intensive use, especially in challenging environmental conditions, the transformer cooling system may struggle to efficiently dissipate heat. This leads to elevated operating temperatures, which:

• Accelerate insulation degradation, weakening its dielectric properties,

• Increase power losses, reducing the device’s overall efficiency,

• Shorten the lifespan of components such as windings or the core.

Modernizing the cooling system enables better heat dissipation, which translates into more efficient transformer operation, even under changing operating conditions. Thanks to advanced solutions like state-of-the-art coolers or high-performance fans, a transformer can operate reliably for many additional years.

- how do we modernize cooling systems?

At Energeks, cooling system modernization is a comprehensive process that includes:

• Inspection of the existing cooling system – we analyze the performance of coolers, fans, and pumps to identify bottlenecks limiting efficiency.

• Designing modern solutions – depending on the needs, we install new coolers that enhance heat dissipation, higher-performance fans, or pumps that support oil circulation.

• System optimization – we implement solutions to improve air and oil flow, ensuring more even cooling of all transformer components.

• Testing and calibration – every modernization ends with performance tests that confirm the effectiveness of the implemented changes.

Our efforts not only improve cooling but also adapt the transformer to new standards and environmental requirements, such as higher ambient temperatures or increased loads from network expansion.

Case Study #6

For a major client in the industrial sector, we modernized the cooling system of a transformer operating at its limit. We installed advanced coolers and additional high-efficiency fans. The result? Transformer efficiency increased by 15%, allowing for an additional 10 hours of weekly operation at full load. Through modernization, the client avoided the costs of purchasing a new device, saving hundreds of thousands of euros.

Cooling system modernization is not just a short-term fix – it’s an investment in the long-term efficiency and safety of the transformer. Here are the key benefits:

• Increased operational efficiency – improved cooling enables the device to work more effectively under higher loads.

• Extended transformer lifespan – reduced overheating slows down insulation and internal component degradation.

• Adaptation to new requirements – modern cooling systems allow operation in more challenging environmental conditions.

At Energeks, we believe every transformer deserves a second chance. Through cooling system modernization, your transformer gains not only a new lease on life but also the capability to meet future challenges. Regular upgrades to cooling systems are a step toward greater energy efficiency and the safety of the entire power network.

7. Installation and Replacement of Accessories: Smart Solutions

Modern transformers are becoming increasingly technologically advanced, and their reliability relies on precise monitoring of key operational parameters. The installation of modern accessories is not just an upgrade – it’s a step toward transformers of the future that can "communicate" with operators and alert them to potential issues before they impact device performance. With smart solutions like sensors, relays, or digital thermometers, it’s possible to continuously monitor the transformer’s condition and quickly respond to any anomalies.

As electrical systems become more complex, the need for precise monitoring of transformer operational parameters is greater than ever. Imagine a transformer working under intense conditions, and the operator has no access to information about oil temperature, pressure, or insulation condition. A lack of such data can lead to overheating, overloading, or even major failures.

Modern accessories, such as DGPT2, PT-100 sensors, or pressure relays, enable continuous monitoring of the transformer's condition. This allows operators to make decisions based on real-time data, minimizing the risk of failures and extending the device's lifespan.

- how does the process of installing and replacing accessories look like?

Energeks focuses on a comprehensive approach to every issue, including the installation and replacement of accessories. This process includes:

• Analyzing client needs – We assess which transformer parameters need monitoring to ensure its safe and efficient operation.

• Selecting the right accessories – We choose modern devices, such as digital thermometers, pressure relays, Buchholz relays, or oil temperature sensors, that best meet the client's needs and transformer requirements.

• Installation and configuration – We install new accessories and integrate them into the existing monitoring system.

• Operator training – We provide support in operating the modern devices, enabling personnel to fully utilize their potential.

Our goal is to deliver solutions that not only enhance safety but also increase the efficiency of transformer management.

Case Study #7

For one of our industrial clients, we modernized a transformer by installing PT-100 sensors to monitor oil temperature and DGPT2 pressure relays. After implementing these modern solutions, operators could quickly detect even the smallest deviations from norms and respond in real time.

The result? Over two years of trouble-free operation, with no overloads leading to failures. The transformer now works at full capacity, and the client significantly improved the efficiency of their energy infrastructure management.

The benefits of accessory installation and replacement:

• Continuous monitoring – Modern sensors and relays provide real-time data on transformer condition.

• Minimized failure risks – Early anomaly detection prevents issues from escalating.

• Increased efficiency and lifespan – Controlled operation enhances the transformer's reliability and durability.

• Compliance with modern standards – Newly installed accessories meet the highest technological requirements.

8.Sealing Oil Leaks

Oil leaks in transformers are like a hole in your favorite mug – you might manage for a while, but sooner or later, everything will spill. Often underestimated or even ignored, oil leaks can be the first sign of more serious issues, such as weakened seals, material degradation, or improper operation of bushings. A small drop of oil on the floor might actually mean your transformer is crying out for help.

Oil leaks are not just the loss of a valuable cooling medium, but also a significant threat to both the transformer and its working environment. What could happen if the issue is ignored?

• Loss of insulation and cooling – Less oil means reduced cooling and insulation effectiveness, leading to overheating and damage.

• Component damage – Oil may seep into places it shouldn’t, causing corrosion or material degradation.

• Environmental and legal costs – Leaks can contaminate the environment, potentially resulting in financial penalties.

And honestly, who would want to see a transformer "crying" oil? Don’t let it happen – we’ll take care of the sealing!

- how do we seal leaks?

Sealing leaks and repairing shields is a process we approach with full commitment at Energeks – because every drop matters. Here's how we do it:

• Diagnosing the source of the leak – First, we identify where the oil is leaking from. Sometimes it’s obvious, and other times we need to play detective.

• Repairing or replacing seals – We remove old, worn-out seals and replace them with new ones that are resistant to operational conditions.

• Regenerating shields – We repair or replace protective components that may have been damaged by time, moisture, or vibrations.

• Leak testing – After repairs, we conduct leak tests to ensure the transformer is fully secure.

We perform all of this quickly and efficiently so your transformer stops "leaking" in every possible way.

Case Study #8

At one industrial facility, we encountered a transformer that had been struggling with an oil leak for an extended period. Oil drops on the floor were ignored for months until the leak grew large enough to reduce the oil level by 10%. Our team quickly located the leak, replaced the damaged seals, and regenerated the shields.

Result? Zero leaks and a transformer ready for continued operation – without "tears" on the floor.

Sealing leaks is an investment that delivers benefits on multiple levels:

• Protecting the equipment – No leaks mean the oil performs its function 100%.

• Cost savings – Avoid expenses related to refilling oil, repairs, or even environmental penalties.

• Professional appearance – A transformer that doesn’t "cry" oil looks better and performs more effectively.

Oil leaks are not just a nuisance; they are a significant warning that something in your transformer needs attention. Don’t let your transformer lose energy and potential.

9. Shield Repair: What Are Shields and Why Are They So Important?

Shields in transformers are protective elements that play a crucial role in safeguarding the equipment from external factors such as rain, dust, snow, or other contaminants. While they may seem less significant compared to the more "technological" components of a transformer, their condition greatly affects the longevity and reliability of the device.

Shields not only protect the transformer from environmental factors but also support efficient cooling by directing airflow to specific areas, thereby preventing overheating. Over time, due to corrosion, vibrations, or mechanical damage, shields can deform, crack, or lose their seal. This can lead to oil leaks and expose the interior of the transformer to harmful external factors.

Think of shields as the armor of your transformer. When they are unsealed or damaged, the transformer becomes more vulnerable to environmental impacts, which can result in:

• Accelerated corrosion of internal and external components,

• Internal contamination that reduces cooling efficiency,

• Oil leaks that lower insulation and cooling levels,

• Airflow disruptions that increase the risk of overheating.

Repairing or replacing shields is not just cosmetic – it’s an action that significantly impacts the durability and efficiency of the entire device.

- how do we repair shields?

At Energeks, the shield repair process is comprehensive and tailored to the specific needs of each transformer. Here's how we do it:

• Inspection of Shield Condition – We assess their structural integrity, check for corrosion, cracks, or deformation, and evaluate their effectiveness in directing airflow.

• Repair of Damaged Components – We straighten deformed shields, remove corrosion, and protect surfaces against further damage using protective coatings.

• Replacement of Irreparably Damaged Parts – For severe damage, we install new shields made of materials resistant to environmental conditions and long-term use.

• Airflow and Seal Tests – After the repair, we test the shields to ensure they perform their functions 100%, both in terms of protection and cooling efficiency.

Case Study #9
At a production facility, a transformer exposed to heavy rainfall and high humidity began to show signs of internal corrosion, and the oil level significantly decreased. Inspection revealed that damaged shields were allowing water to penetrate the device, contaminating the oil and reducing cooling effectiveness. Our team repaired the shields, sealed their joints, and applied an anti-corrosion coating. The result? The transformer regained full tightness, and the risk of failure was completely eliminated.

If your transformer is "losing its armor" and starting to leak, act quickly. We will seal the leaks, repair the shields, and ensure your equipment operates reliably for years to come. Don’t ignore small drops – each one could be the beginning of a bigger problem!

Transformer Modernization in Numbers

A transformer is the heart of every energy infrastructure – its reliability impacts the entire network, and a failure can lead to not only downtime but also enormous financial losses. In heavily utilized industrial environments, transformers often operate at the limits of their capacity, with harsh conditions, high loads, or contamination accelerating the degradation of insulation and other critical components.

The statistics are clear – as much as 70% of transformer failures result from insulation degradation, which can be prevented through regular inspections and proper servicing.

With diagnostics and transformer oil regeneration, you can reduce the risk of such scenarios by up to 40%. Oil analyses help detect micro-leaks or initial electrical discharges, while regeneration removes contaminants and restores the oil’s full cooling and insulation efficiency. Each service is a step towards peace of mind – you know your equipment is running optimally, avoiding costly surprises.

A transformer overhaul is not just about preventing failures – it is also a perfect opportunity for modernization. Changing the winding connection group, installing modern accessories, or replacing cooling systems can improve the unit's efficiency by up to 20% and extend its lifespan by several decades!
