The characteristics of the various transformer connections and possible operating problems under normal or abnormal conditions are treated for three-phase distribution systems. These systems are characterized by primary voltages up…
Recommendations are made regarding oil tests and evaluation procedures; methods of reconditioning and reclaiming conventional petroleum (mineral) dielectric oils; the levels at which these methods become necessary; and the routines…
SUPERSEDED BY IEEE STC C57.106-2002 (SH/SS95008) NOT AVAILABLE TO RESELLERS This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers.
Recommendations regarding oil tests and evaluation procedures are made in this guide;references are made to methods of reconditioning and reclaiming conventional petroleum (mineral) dielectric insulating oils;the levels at which these…
Recommendations believed essential for the application of overcurrent protective devices applied to limit the exposure time of transformers to short circuit current are set forth. Transformer coordination curves are presented…
Recommendations believed essential for the application of over current protective devices applied to limit the exposure time of transformers to short-circuit current are set forth. Transformer coordination curves are presented…
The purpose of the report is to establish uniform methods for determining the capability of transformers to supply nonsinusoidal load currents, without loss of normal life expectancy. Two methods are…
Superseded by IEEE Std C57.110-2008. Methods are developed to conservatively evaluate the feasibility of supplying additional nonsinusoidal load currents from an existing installed dry-type or liquified transformer, as a portion…
Tests and evaluation procedures for silicone transformer fluid are recommended. Criteria for maintenance and methods of reconditioning silicone fluid are described. The aim is to assist the transformer operator in…
