More info
Description / Abstract:
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.
