Characteristics relating to performance, limited electrical and mechanical interchangeability, and guidance to assist in the proper selection of sealed dry-type transformers are provided in this standard. Specific rating combinations are described in the range from 750 to 5000 kVA inclusive, with high-voltage 2400 to 34500 Volts inclusive and low-voltage 208Y/120 to 4160 Volts inclusive. Sealed dry-type...
This standard covers electrical and mechanical performance and test requirements for tap changers installed in voltage regulating power and distribution transformers of all voltage and kVA ratings. It covers load tap changers (LTCs), also known as on-load tap changers (OLTCs), which can change taps while the transformer is energized and carrying load; and it covers de-energized tap changers (DETCs),...
