Transformer Oil Testing Services

Where Clean Oil Meets Reliable Power.

Oorja Technical Services Pvt. Ltd, an NABL-accredited transformer oil testing laboratory, delivers accurate, fast, and reliable results for all types of transformers from small distribution units to large power transformers.

We specialise in complete transformer oil analysis, including dissolved gas analysis of transformer oil, BDV test of transformer oil, moisture testing, acidity checks, and furan analysis of transformer oil. Our team follows IS 335, IEC 60296, and other international standards for every test.

Whether you need routine insulating oil testing or emergency diagnostics, we provide both lab-based and on-site testing services across India. With a pan-India team of experienced engineers and modern equipment, OTSPL ensures you get precise insights wherever you are located.

WHY TEST TRANSFORMER OIL REGULARLY?

Transformer oil works hard 24x7. Without proper checking, you may face:

• Insulation failure causing short circuits
• Overheating issues from poor cooling
• Flashovers due to moisture in oil
• Paper insulation damage that cannot be repaired
• Sudden breakdowns and high repair costs

Think of transformer oil analysis as a regular health check-up. It tells you what's going wrong before the transformer fails.

TESTS WE OFFER FOR TRANSFORMER OIL

Our transformer oil testing laboratory has modern equipment to perform all tests mentioned in IS 335, IS 1866, IEC 60296, and other standards.

DETAILED LOOK AT IMPORTANT TESTS

Breakdown Voltage (BDV) Test

The BDV test of transformer oil is the first test anyone does. It tells you if the oil can handle high voltage or not.

We use an automatic bdv tester for this. Two electrodes sit inside the oil, and the voltage increases slowly. When a spark happens, that voltage is recorded as the breakdown value.

Why this test matters:

• Low BDV means moisture or dirt in the oil
• Regular bdv of transformer oil checks the dielectric health
• Helps decide if oil filtration is needed

BDV oil test follows IS 335 and IEC 60296. For good transformers, BDV should be above 40 kV. New oil should give above 50 kV.

Dissolved Gas Analysis (DGA)

Dissolved gas analysis of transformer oil is like a blood test for transformers. When something goes wrong inside — arcing, heating, or discharge — the oil breaks down and releases gases.

Our DGA analysis of transformer oil finds these gases:

DGA test of transformer oil follows IEC 60567. Our DGA transformer experts analyse gas ratios to determine exactly what fault is occurring.

Furan Analysis

Furan analysis of transformer oil is special because it checks the paper insulation, not the oil. Paper cannot be replaced easily. Once the paper is damaged, transformer life reduces.

Our furan test transformer analysis measures:

• 2-furaldehyde (2-FAL)
• Other furanic compounds

If furan levels are high, the paper is degrading. This helps you plan replacement before failure.

Acidity Test

The acidity test of transformer oil measures acids formed when oil oxidises. High acid means:

• Sludge will form soon
• Metal parts may corrode
• The paper will degrade faster
• Cooling will reduce

Regular acidity check tells you when to change or recondition oil.
