scope:
This standard is for sealed dry-type transformers, 501 kVA and larger, with high-voltage 601 to 34500 volts inclusive and low-voltage 208Y/120 to 4160 volts inclusive. This standard is intended to set forth characteristics relating to performance, limited electrical and mechanical interchangeability, and to assist in the proper selection of such equipment.
This standard does not apply to other types of transformers, such as specialty, ventilated dry-type, padmounted dry-type, liquid immersed, instrument, regulating, furnace, mine, and rectifier operations.
Purpose
This standard describes certain electrical and mechanical characteristics of 60-Hz, two-winding, threephase, sealed dry-type transformers rated 501 kVA and larger, generally used for step down purposes. This standard will accomplish this by presenting basic electrical and mechanical requirements and describing other requirements or alternatives that may be specified for some applications.
