IEEE Standard Test Code for Liquid-Immersed Distribution, Power, and Regulating Transformers
Also Known As: IEEE Std C57.12.90-2015
IEEE C57.12.90-2015 is a standard that outlines the methods for conducting tests on liquid-immersed distribution, power, and regulating transformers. The standard excludes certain types of transformers such as instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, and mine transformers.
The standard covers a wide range of tests including 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.
The scope of the standard is to provide a basis for the performance and proper testing of liquid-immersed transformers. It is intended for use by professionals involved in the testing and evaluation of these transformers. Transformer requirements and specific test criteria are not included in the standard, but can be found in other appropriate standards or user specifications.
The purpose of the standard is to provide information on the test procedures specified in IEEE Std C57.12.00 and other applicable standards. It serves as a guide for conducting tests on liquid-immersed distribution, power, and regulating transformers, ensuring that the testing is done correctly and accurately.
