“Transformer oil and other insulating liquids suffer from electrical and mechanical stresses while a transformer is in operation.”

Testing of Transformer Oil

Transformer oil and other insulating liquids suffer from electrical and mechanical stresses while a transformer is in operation. In addition there are contaminations caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature. As a result the original chemical properties of Transformer Oil changes gradually, rendering it ineffective for its intended purpose after many years. Hence this oil has to be periodically tested to ascertain its basic electrical properties, and make sure it is suitable for further use or initiate necessary actions like filtration/regeneration.

Transformer Oil is not only subject to its own degradation, but is also a carrier of gasses emanated during arcing or flashovers between paper and winding insulations. Transformer Oil Testing and Analysis provides important information regarding any such incipient faults, without the need to pull down the equipment from its running condition.
