IEEE C57.131

Requirements for Tap Changers

inactive
Buy Now
Organization: IEEE
Publication Date: 1 January 1995
Status: inactive
Page Count: 46
scope:

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.
