FIELD: electricity.
SUBSTANCE: invention refers to the field of electric engineering. Device contains protective diode, power switch, current sensor, discharge diode, reactor coil, condenser, uninterrupted power supply with built-in accumulator battery, input voltage sensor, voltage control and load voltage first-order time derivative signal generation sensor, microcontroller, non-volatile memory, random-access memory, real-time clock, power switch control driver, analog-digital converter, data bus adapter, communication bus, external control system and load.
EFFECT: performing operational readjustment of technical characteristics (reprogramming) of intellectual filter both for recording parameters of pulse switching overvoltages intrinsic to various electrical networks and to meet requirements of various loads (crucial and particularly sensitive to pulse switching overvoltages and interference).
