Method and apparatus for connecting capacitors in transformer substations

Abstract

In the developed system for the unloading of the electric network from the reactive power, containing capacitors and the adjustable part based on the booster transformer and the transistor converter, dynamic regimes are examined when switching capacitors on and off. It is proposed to supplement the system under consideration with an electronic electrical apparatus that allows connecting and disconnecting capacitors with high speed, without current surges and without affecting the voltage of consumers.
