FIELD: electricity.
SUBSTANCE: device for start-up and compensation of reactive power comprises capacitors connected to ends of stator winding, which in the specified point of the transition mode automatically switch from "star to delta".
EFFECT: limitation of start-up current in process of start-up and compensation of reactive power of the induction motor in working mode, increased efficiency and reliability of the device due to switching of stator winding connection from start with serial connection of capacitors at start-up to delta with parallel connection of capacitors to the network in working mode.
