Liquid Dielectrics Laboratory for Transformer Oil

Discover various laboratories of ERDA for your testing needs

Liquid Dielectric Laboratory

Safe operation of transformer is very important in power supply and distribution systems. It is, therefore, essential to monitor condition of transformer on continual basis. Evaluation of quality of transformer oil is one of the important tools to monitor condition of transformer. ERDA has facilities to evaluate new transformer oil i.e. before it is put in use or used oil taken-out from working transformer during its use.
