FIELD: electric power engineering.
SUBSTANCE: invention relates to electric power engineering and can be used to reduce level of switching overvoltage on electric equipment, in particular, to high-voltage motors and transformers operating in networks. Device comprises three star-connected capacitors (1), common point of which is grounded through resistor (2).
EFFECT: reduced weight and dimensions of the device and higher efficiency.
