Breakdown Voltage Test of Transformer Oil

Be it a transformer, a high voltage cable or a capacitor – any type of high voltage apparatus must be
maintained properly and timely. However, transformers are one of the most important elements of the power grid to be kept up-to-date as they are the main distributors of alternating current electrical energy. Both homes and businesses, actually, whole cities depend on their proper operation for stable energy supply.

Regular transformer oil testing is a crucial preventative measure that will help you keep your high voltage devices up and running. The dielectric liquid deteriorates over time due to moisture and impurities, losing its cooling and insulating properties. A common method for checking the oil quality is measuring its breakdown voltage.

Conducting the oil testing procedure periodically, you can keep the hydrocarbon fluids of the oil pure and keep its breakdown voltage high, which optimizes the overall transformer performance. Just take a sample of the dielectric liquid, fill it into the vessel of an oil dielectric tester (like one of the KEP OLT models), run a test, get the oil breakdown voltage and compare it with that set in one of the numerous standards.

KEP’s OLT oil dielectric testers provide an easy and reliable way to measure the breakdown voltage of dielectric liquids. These portable solutions allow to automatically run the whole testing process, which saves a lot of time and money.
