Description

При исчезновении тока в первичной обмотке последовательного трансформатора, св занном с отключением линии или защищаемого трансформатора, исчезает напр жение с выхода датчика тока 4 и устройство не работает.When the current in the primary winding of the serial transformer, connected with the disconnection of the line or the protected transformer, disappears, the voltage from the output of the current sensor 4 disappears and the device does not work.
