C57.12.90-2021

IEEE Draft Standard Test Code for Liquid-Immersed Distribution, Power, and Regulating Transformers

Methods for performing tests specified in IEEE Std C57.12.00™ and other standards 1 applicable to liquid-immersed distribution, power, and regulating transformers are described. 2 Instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, and mine transformers are excluded. Resistance measurements, polarity and phase-relation 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, and calculated data are covered in this standard.
