IEEE C57.12.90

Abstract

This standard describes methods for performing tests specified in IEEE Std C57.12.00&#8482; and other standards applicable to liquid-immersed distribution, power, and regulating transformers.1 It is intended for use as a basis for performance and proper testing of such transformers. <br>This standard applies to all liquid-immersed transformers, except instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, and mine transformers. <br>Transformer requirements and specific test criteria are not a part of this standard, but they are contained in appropriate standards, such as IEEE Std C57.12.00, ANSI C57.12.10 [B1],² IEEE Std C57.12.20&#8482;, and IEEE Std C57.12.40&#8482; [B10], or in user specifications. <br><strong>Purpose</strong> <br>The purpose of this standard is to provide test procedure information for tests specified in IEEE Std C57.12.00 and other standards applicable to liquid-immersed distribution, power, and regulating transformers. It is intended for use as a basis for performance and proper testing of such transformers. <br>¹ Information on references can be found in Clause 2. <br>² The numbers in brackets correspond to the numbers in the bibliography in Annex C.
