METHOD OF MEASURING MAGNETIC LOSSES IN MAGNETIC CIRCUIT OF SINGLE-PHASE TRANSFORMER UNDER WORKING CONDITIONS

摘要

FIELD: instrument engineering.;SUBSTANCE: massifs of instant values of currents and voltages of transformer's windings are registered under working condition at known frequency of feeding circuit and transformation coefficients of transformer. Then these currents and voltages are derived to primary circuit and massive of instant arithmetic means of derived voltages at windings of transformer is found.;EFFECT: widened functional abilities.;3 dwg, 2 tbl
