DEVICE FOR DEEP CLIPPING OVERVOLTAGE IN DISTRIBUTING ELECTRIC POWER DEVICE HAVING INSULATED OR COMPENSATED NEUTRAL WIRE Russian patent published in 1995 - IPC

Abstract RU 2040841 C1

FIELD: electric engineering. SUBSTANCE: device has clipper of overvoltage with low level of overvoltage clipping, AND gate, delay gate. This results in possibility to clip voltage to level 2-2,3 U_ϕ when device is short-circuited to earth. In this case switch of connection where overvoltage clipper is connected is opened. EFFECT: decreased time when linear voltage of supply line supplies overvoltage clipper. 1 dwg
