Transformer testing at this Bahadurgarh, Haryana facility covered insulation resistance testing, power factor (dielectric loss) testing, and dissolved gas analysis (DGA) of the transformer oil — three tests that together catch the majority of failure modes before they cause an outage. Winding insulation failure accounts for roughly 20–30% of transformer failures, according to IEEE and CIGRE survey data, making insulation-focused testing the single highest-value item in a transformer testing programme, ahead of visual inspection alone. Oil and gas facilities carry particular stakes here: an unplanned transformer failure doesn’t just cause downtime, it can affect process safety systems that depend on continuous, reliable power, and transformer oil itself is a fire risk that compounds if a failing unit isn’t caught early. At this facility, testing established a baseline against which future tests get compared — power factor testing specifically is more valuable as a trend over time than as a single reading, since a transformer moving from 0.4% to 1.2% power factor over a few years indicates active degradation even if 1.2% is still technically within an acceptable range on its own. Transformer testing for an industrial facility typically costs ₹30,000–₹1.5 lakh per unit depending on transformer size and the specific tests included. This case study covers the specific test results and what they indicated about the transformer’s condition.
This case study covers insulation resistance, power factor, and dissolved gas analysis (DGA) testing on transformers at an oil & gas facility — the three tests that together catch roughly 20-30% of failures traced to winding insulation.

Power Quality Analysis: What it is and Why it Matters
Power quality analysis refers to the assessment of the quality of electrical power supplied to a system or equipment. It involves measuring various parameters such as voltage fluctuations, harmonics, transients, and interruptions. Power quality analysis is crucial for industries as it helps ensure that electrical systems operate efficiently and reliably.
Power quality issues can have a significant impact on electrical systems. Voltage fluctuations can cause equipment malfunctions or failures, leading to costly downtime. Harmonics, which are unwanted frequencies superimposed on the fundamental frequency, can cause overheating in transformers and other equipment. Transients, which are sudden changes in voltage or current, can damage sensitive electronic devices.
By conducting power quality analysis, industries can identify any power quality issues and take necessary measures to mitigate them. This can include installing power conditioning equipment, implementing voltage regulation measures, or improving grounding systems. Ultimately, power quality analysis helps improve the reliability and efficiency of electrical systems.
Benefits of Power Audit for OIL & Gas Companies
A power audit is a comprehensive assessment of an organization’s electrical system and power consumption. It involves analyzing energy usage patterns, identifying areas of inefficiency, and recommending measures to optimize energy consumption. Conducting a power audit can provide several benefits for OIL & Gas Companies.
Firstly, a power audit helps identify areas of energy wastage and inefficiency. This can include equipment running at suboptimal levels, inefficient lighting systems, or poor insulation. By identifying these areas, OIL & Gas Companies can implement energy-saving measures and reduce their overall energy consumption.
Secondly, a power audit helps identify potential risks or issues in the electrical system. This can include overloaded circuits, faulty wiring, or outdated equipment. By addressing these issues, OIL & Gas Companies can improve the safety and reliability of their electrical systems.
Lastly, a power audit helps OIL & Gas Companies comply with energy efficiency regulations and standards. Many countries have implemented energy efficiency targets and regulations to reduce carbon emissions and promote sustainable practices. By conducting a power audit, OIL & Gas Companies can ensure that they are meeting these requirements and contributing to a greener future.
Harmonic Analysis: Understanding the Impact of Harmonics on Electrical Systems
Harmonics are unwanted frequencies that are superimposed on the fundamental frequency in an electrical system. They are caused by non-linear loads such as variable frequency drives, rectifiers, and electronic devices. Harmonics can have a significant impact on electrical systems and equipment.
One of the main effects of harmonics is increased heating in transformers, motors, and other equipment. This can lead to premature aging, reduced lifespan, and increased maintenance costs. Harmonics can also cause voltage distortion, leading to equipment malfunctions or failures. In extreme cases, harmonics can cause electrical fires or explosions.
Conducting harmonic analysis helps identify the presence and severity of harmonics in an electrical system. This analysis involves measuring harmonic currents and voltages, assessing their impact on the system, and recommending measures to mitigate their effects. By addressing harmonics, OIL & Gas Companies can improve the reliability and efficiency of their electrical systems.
