Test Parameters

WHY ABIRAMI FOR TRANSFORMER OIL TESTING

  1. Accuracy
  2. Proper diagnosis of the fault
  3. Solution for the fault
  4. Total restoration with no further loss of time and revenue.
  5. More than 20 years of experience with an  estimated 450  power transformers repaired.

We are having following testing facilities for transformer oil

1. BDV  (BREAK DOWN VOLTAGE)
2. IFT (INTERFACIAL TENSION)
3. FLASH POINT
4. ACIDITY KIT (NEUTRALIZATION KIT)
5. WATER CONTENT(PPM)
6. CAPACITANCE TAN DELTA AND RESISTIVITY
7. DISSOLVED GAS ANALYSER (DGA)
8. MULTIPLE GAS EXTRACTOR
9. DENSITY
10. SLUDGE
11. KINEMATIC VISCOSITY*

1. BDV (Break Down Voltage)
The Voltage at which the oil breaks down when subjected of AC electric field with A continuous voltage raise.

2. IFT (Interfacial Tension)
This instrument used for measuring under non-equilibrium condition the Interfacial Tension of mineral Oils against water, which has been shown by practice to give reliable indication of the presence of hydrophilic compounds.

3. FLASH POINT
This Instrument used for measuring the Flash Point by pensky martens closed cup Tester of fuel oils, lubricating oils, Suspensions of solids, liquids that tend to form a surface film under test conditions and other liquids. .

4. ACIDITY KIT (NEUTRALIZATION KIT)
This Instrument used for the determination of acidic constituents in Transformer oil. This acid number is used as a guide in the quality of Transformer oil. description

5. WATER CONTENT(PPM)
This Instrument used for the determination of water content in unused or used insulating liquids with coulometrically generated Karl Fischer regent. We can measure from 1 ppm to 100 ppm.

6. CAPACITANCE TAN DELTA AND RESISTIVITY
This testing instrument to measure three important parameter Tan Delta, Dielectric Constant and Resistivity of an insulating medium. Tan delta and Dielectric Constant balance with the aid of a synchronous and phase sensitive null detector.

7. DISSOLVED GAS ANALYSER (DGA)
DGA is the most sensitive and reliable loss prevention technique and it gives an early indication of abnormal behaviour of transformer. This instrument measure the concentrations of dissolved gas or free gases and be interpreted to diagnose the condition of oil filled electrical equipment in service and suggest future action.

8. MULTIPLE GAS EXTRACTOR
This instrument used for extracting dissolved gas from transformer oil.

9. DENSITY
Density is significant in determining the quality of an oil and may be useful for type identification or to suggest marked compositional changes.
