Abstract

PURPOSE: To prevent the unnecessary action of current differential elements, by facilitating action by mounting making current detecting elements formed in the case when making a transformer to each phase and by varying the detecting sensitivity of the making current detecting elements of the other phases while using the action of making current detecting elements even at one phase as a condition when the elements function even at one phase.
CONSTITUTION: Making current detecting elements (64R∼64T) formed in the case when making a transformer 1 are mounted to each phase (Phase R∼Phase T), action is facilitated by varying the detecting sensitivity of the making current detecting elements of the other phases while employing the action of making current detecting elements even at one phase as a condition when the elements works even at one phase, and the unnecessary action of current differential elements by making current can be prevented.
