IEEE C57.131-1995

This standard covers electrical and mechanical performance and test requirements for load tap changers installed in power transformers and voltage regulating transformers of all voltage and kVA ratings. It relates mainly to load tap changers immersed in transformer mineral oil, but may also be used for other insulating fluids insofar as conditions are applicable.

The purpose of this standard is to provide standard performance and test requirements for load tap changers.

New IEEE Standard - Superseded. Electrical and mechanical performance and test requirements for load tap changers installed in power transformers and voltage regulating transformers of all voltage and kVA ratings are covered.
