Transformer Oil Test Lab(NABL)
NABL Accredited Testing Laboratory as Per ISO/IEC 17025:2005

We have NABL Approved Transformer oil test laboratory and render our service on short calls as and when required by you with our expert comments and suggestion promptly.

  • Dissolved Gas Analysis (DGA)
  • Interfacial Tension (IFT)
  • Neutralization Number (Acidity)
  • Sludge
  • Dielectric Strength (BDV)
  • Flash point
  • Dielectric Dissipation Factor (Tan Delta)
  • Moisture Content (PPM)
  • Density
  • Resistivity
 
 
 

BDV (BREAK DOWN VOLTAGE)
The voltage at which the transformer oil breaks down when subjected of AC electric field with a Continuous voltage raise.

 
     
IFT (INTERFACIAL TENSION)
This instrument used for measuring, under non-equilibrium condition, the Interfacial tension of mineral oil S against water, which has been shown by practice to give reliable indication of the presence of hydrophilic compounds in transformer oil.
 
     
FLASH POINT
This instrument used for measuring the Flash Point by Pensky Martens closed cup tester of transformer oil, fuel oils, lubricating oils, Suspension of solids, liquids that tend to form a surface film under test conditions and other liquids.
 
     
ACIDITY(NEUTRALIZATION NUMBER)
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.
 
     
WATER CONTENT (PPM)
This Instrument used for the determination of water content in transformer oil unused or used insulating liquids with coulometrically generated Karl Fischer regent. We can measure from 1 ppm to 100 ppm.

Capacitance, Tan Delta and Resistivity
This testing instrument to measure three important parameter in transformer oil - 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.
 
     
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 in transformer oil and be interpreted to diagnose the condition of transformer oil filled electrical equipment in service and suggest future action.
 
     
MULTIPLE GAS EXTRACTOR
This instrument used for extracting dissolved gas from transformer oil.
 
     
DENSITY
Density is significant in determining the quality of an transformer oil and may be useful for type identification or to suggest marked compositional changes.
