Revision Standard - Superseded. Methods for performing tests specified in IEEE Std C57.12.00TM-2006 and other standards applicable to liquid-immersed distribution, power, and regulating transformers are described. Instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, and mine transformers are excluded. This standard covers resistance measurements, polarity and phaserelation tests, ratio tests, no-load-loss and excitation current measurements, impedance and load loss measurements, dielectric tests, temperature tests, short-circuit tests, audible sound level measurements, calculated data, and certified test data.
This standard describes methods for performing 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, safety, 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. This standard is being revised to include technical changes to the document, which have been proposed by various technical working groups and sub-committees within the PES Transformers Committee. As this standard describes the standard test code for liquid immersed distribution, power and regulating transformers it is the intention of the working group to keep it as up-to-date as possible.
