NEMA - NEMA TR 1 - TRANSFORMERS, STEP VOLTAGE REGULATORS AND REACTORS Organization: NEMA
Date: 2013-01-01
Description: This standards publication applies to single phase and poly phase power and distribution transformers (including step-voltage regulators and reactors). This standard excludes dry type transformers covered by NEMA ST20. This publication provides a reference list of applicable ANSI and IEEE C57 standards.
NEMA - NEMA ST 20 - DRY-TYPE TRANSFORMERS FOR GENERAL APPLICATIONS Organization: NEMA
Date: 2014-01-01
Description: It applies to transformers with and/or without accessories having ratings of 1.2 kV class, 0.25 kVA through 4000 kVA. Transformers not covered by this standard may be covered by NEMA TR 1. This standards publication applies to transformers, commonly known as general-purpose transformers for commercial, institutional and industrial use in nonhazardous locations both indoors and outdoors.
