Methods for performing tests specified in IEEE Std C57.12.00(TM) 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. 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.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>1<b><\/td>\n<td>IEEE Std C57.12.90\u2122-2015\/Cor. 1-2017 Front Cover  <\/td>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>Title page  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>Important Notices and Disclaimers  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>Participants  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>Contents  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>8.
