Recommended Practice for Routine Impulse Tests for Distribution Transformers

This recommended practice covers routine impulse tests performed on distribution transformers, as required in IEEE Std C57.12.00(TM), and described in 10.4 of IEEE Std C57.12.90(TM)-2021(1). Distribution transformers covered by this recommended practice are overhead, pad mounted, and underground liquid-immersed distribution transformers with requirements specified in IEEE Std C57.12.20, IEEE Std C57.12.23, IEEE Std C57.12.24, IEEE Std C57.12.34, IEEE C57.12.36, IEEE Std C57.12.38 and IEEE Std C57.12.40. This recommended practice covers only those aspects of impulse testing that are specific to routine testing of distribution transformers. For more thorough coverage of impulse testing of transformers in general, IEEE Std C57.98(TM) should be consulted.

C57.138-2016

IEEE Recommended Practice for Routine Impulse Tests for Distribution Transformers

General test procedures for performing routine quality control tests that are suitable for high-volume, production line testing are included in this recommended practice. Transformer connections, test methods, circuit configurations, and failure detection methods are addressed. This recommended practice covers liquid-immersed, single- and three-phase distribution transformers.
