PC57.12.90 - Standard Test Code for Liquid-Immersed Distribution, Power, and Regulating Transformers
Project Details
This standard describes methods for performing tests specified in IEEE Std C57.12.00(TM) 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. 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. 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, IEEE Std C57.12.10(TM), IEEE Std C57.12.20(TM), and IEEE Std C57.12.40(TM), or in user specifications.
