Transformer & Insulating Oil Testing (Outsource)

We offer consultancy services for Transformer Oil Testing, It’s methods are a vital part of any maintenance program. An annual DGA is the most crucial test for the liquid lining. Analysis of gases in the oil can specify insulation overheating/ overloading, corona discharge, liquid overheating, or arcing in the transformer. The screen test comprises additional physical, chemical, and electrical tests; this includes power factor, interfacial tension, acidity, colour, and dielectric breakdown. No single test alone can indicate the authentic stature of the liquid. Thus, it is necessary to perform all the tests. Furthermore, a useful test is performed by transformer oil labs that include those for water content, PCBs furanic compounds, and metals-in-oil.

What is transformer oil testing?

Transformer oil testing is a method of measuring breakdown voltage and various chemical and physical properties of the transformer oil, either in the laboratory or by using any sort of portable test equipment on site.

What are oil transformer testing methods?
