Dielectric-WGC57.138 - Dielectric Tests - Rev. routine impulse test for distribution transformers
|Working Group Chair||
|IEEE Program Manager|
Transformer connections, test methods, circuit configurations, and failure analysis of lightning impulse and switching impulse testing of power transformers are addressed. This guide is also generally applicable to distribution and instrument transformers.
Guidance on the use of outdoor power apparatus bushings is provided. The bushings are limited to those built in accordance with IEEE Std C57.19.00-1991. General information and recommendations for the application of power apparatus bushings, when incorporated as part of power transformers, power circuit breakers, and isolated-phase bus, are provided.
IEEE C57.138-1998 - IEEE Recommended Practice for Routine Impulse Test for Distribution Transformers
General test procedures for performing routine quality control test that is suitable for high-volume, production line testing. Transformer connections, test methods, circuit configurations, and failure detection methods are addressed. This recommended practice covers liquid-immersed, single-and three-phase distribution transformers.
