Abstract

FIELD: electrical engineering. SUBSTANCE: three phases voltage is simultaneously applied to exclude induction impedance of power net transformer windings influence while metering voltage jumping which permits secondary winding terminals determining by galvanometer using. EFFECT: more useful method for power net equipment adjustment.

Способ относится к области измерения переменных величин, в частности к способу определения полярности выводов обмоток встроенных трансформаторов тока при монтаже и наладке силовых трансформаторов и автотрансформаторов. Способ заключается в том, что напряжение постоянного тока подают одновременно на три фазы, исключая тем самым индуктивное сопротивление обмоток силового трансформатора из цепи постоянного тока, создавая возможность постоянному току изменяться скачком от нуля и проявляться во вторичной обмотке ВТТ на гальванометре.The method relates to the field of measuring variables, in particular to a method for determining the polarity of the terminals of the windings of the built-in current transformers during installation and commissioning of power transformers and autotransformers. The method consists in the fact that the DC voltage is applied simultaneously to three phases, thereby eliminating the inductive resistance of the power transformer windings from the DC circuit, making it possible for the direct current to change abruptly from zero and appear in the secondary VTT winding on a galvanometer.
