Abstracts

Standard

This recommended practice provides calculation methods to conservatively evaluate the feasibility for an existing installed dry-type or liquid-filled transformer, to supply nonsinusoidal load currents as a portion of the total load. This recommended practice also provides necessary application information to assist in properly specifying a new transformer expected to carry a load, a portion of which is composed of nonsinusoidal load currents. A number of examples illustrating these methods and calculations are presented. Reference annexes provide a comparison of the document calculations to calculations found in other industry standards. Suggested temperature rise calculation methods are detailed for reference purposes.

C57.110-1998 - IEEE Recommended Practice for Establishing Transformer Capability When Supplying Non-sinusoidal Load Currents
January 1, 1998 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Methods are developed to conservatively evaluate the feasibility of supplying additional nonsinusoidal load currents from an existing installed dry-type or liquid-filled transformer, as a portion of the total load. Clarification of the necessary application information is provided to assist in prope...

C57.110-1986 - IEEE Recommended Practice for Establishing Transformer Capability When Supplying Non-sinusoidal Load Currents
January 1, 1988 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The purpose of the report is to establish uniform methods for determining the capability of transformers to supply nonsinusoidal load currents, without loss of normal life expectancy. Two methods are described. The first is intended for use by those with access to detailed information on loss densit...
