IEEE 389-1979

New IEEE Standard - Superseded. Superseded This document presents a number of tests for use in determining the significant parameters and performance characteristics of electronic transformers and inductors. These tests are primarily designed for transformers and inductors used in all types of electronic applications, but they are also applicable to many other types of transformers, except transformers of large apparent-power rating used in the electric power industry. Many of the tests described are applicable as means of specifying the required testing of transformers for specific applications.
