Abstract

Inventia se refera la o instalatie pentru masurarea erorii compuse la transformatoarele de curent, ce utilizeaza un sunt etalon pentru masurarea curentului primar de încercare, un alt sunt coaxial al carui coeficient de transfer nu depinde de raportul de transformare al transformatorului de curent încercat pentru masurarea curentului secundar al transformatorului de curent de încercare, iar pentru reglarea componentei aperiodice a curentului primar se utilizeaza un scurtcircuit sincron.The invention relates to a device for measuring the composite error of current transformers using one standard for measuring the primary test current, another being coaxial whose transfer coefficient does not depend on the transformation ratio of the current transformer tested for measuring the current secondary current of the test current transformer and a synchronous short circuit is used to adjust the aperiodic component of the primary current.
