the transformer oil (insulation oil) of voltage- and current-transformers fulfills the purpose of insulating as well as cooling. thus, the dielectric quality of transformer oil is essential to secure operation of a transformer.









































as transformer oil deteriorates through aging and moisture ingress, transformer oil should, depending on economics, transformer duty and other factors, be tested periodically. power utility companies have a vested interest in periodic oil testing since transformers represent a large proportion of their total assets. through such testing, transformers' life can be substantially increased, thus delaying new investment of replacement transformer assets.
