New IEEE Standard - Superseded.

Superseded by IEEE Std C57.12.20-2005.

This standard covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of single- and three-phase, 60-Hz, mineral-oil-immersed, self-cooled, overhead-type distribution transformers 500 kVA and smaller, with high voltages 34500 volts and below and low voltages 7970/13800Y volts and below.

Such transformers may include one or more of the following features:

High-voltage, overcurrent protection;
High-voltage, overvoltage protection;
Low-voltage, overcurrent protection;
Low-voltage, overvoltage protection.

This standard is intended for use as a basis for determining the performance, interchangeability, and safety of the equipment covered, and to assist in the proper selection of such equipment.
