METHOD OF MEASUREMENT OF MAGNETISING CURRENT OF TRANSFORMER THAT OPERATES UNDER LOAD

摘要

FIELD: electromechanics. ^ SUBSTANCE: suggested method consists in the following: measurements of instantaneous value of magnetising current is carried out from two shunts, one of which is included into primary winding of transformer, and the second one is included in the secondary winding, at that measuring terminals of shunts are connected serially back-to-back, and shunts are calibrated so that ratio of voltage drops in shunts during flowing of same current is equal to transformer transformation ratio. ^ EFFECT: development of method for measurement of magnetising current of transformer that operates under load. ^ 4 dwg
