Abstract
PURPOSE: Taking into a consideration the fact that a short-circuited current has a rapid build-up characteristic different from other varying currents, the differential amount of short-circuited current i.e. a varying rate to time is detected to form a current limitig reactor of a low cost and small construction, having a short operating time.
