Organization: IEEE
Publication Date: 11 December 2013
Status: active
Page Count: 25
scope:

This standard provides requirements to demonstrate the adequacy of new Class IE transformers, located in a mild environment of a nuclear power generating station as defined in IEEE Std 323™1, to perform their required safety functions under postulated service conditions. This standard applies to single- and threephase transformers rated 601 V to 15 000 V for the highest voltage winding and up to 2500 kVA (base rating).

Purpose

The purpose of this standard is to provide specific qualification procedures for Class lE transformers to demonstrate their capability to meet the requirements of IEEE Std 323. The transformer shall perform its intended function under all specified service conditions.
