OVERVOLTAGE PROTECTION ELEMENT Russian patent published in 2014 - IPC H02H9/04

Abstract RU 2523703 C2

FIELD: electricity.

SUBSTANCE: invention describes overvoltage protection element with a case and at least one overvoltage limiting component installed inside the case, primarily gas-filled discharger (1), spark discharger, protective diode (2), or variable resistor. According to invention, monitoring of functioning and state of overvoltage protection element during operation is enabled by correlation of overvoltage limiting component with monitoring component registering current (i) flowing through overvoltage limiting component, and by installation of result processing unit evaluating signal from the monitoring component.

EFFECT: enabled monitoring of functioning and state of overvoltage protection element during operation.
