FIELD: electric power systems. SUBSTANCE: device for monitoring of power capacitor bank consists of "n" series-connected rows. Every row includes "m" power capacitors positioned in parallel. Series-connected high-voltage capacitor and two low-voltage capacitors are connected in parallel to power capacitors. DC voltage capacitor is connected in parallel to one of low-voltage capacitors by means of two diodes. DC voltage capacitor is connected to voltage-regulator diode via resistor. Second DC voltage capacitor is connected in parallel to second L-low-voltage capacitor with the air of two diodes. Lead of second DC voltage capacitor is connected to voltage-regulator diode through light-emitting diode connected optically to input of fiber-optical cable intended for connection of its output to control panel of personal on duty. EFFECT: higher reliability in operation. 1 dwg
