The follow-up circuit of basic harmonic wattless power compensation with adjustable value together with filtering of third harmonic in the medium or high voltage power grid

摘要

The continuous system of compensation of primary harmonic passive power at regulated value, together with the filtering of the third harmonic power grid at medium or high voltage, consists of a power transformer (1),a filter transformer (2) with one medium voltage (SN) or high voltage (WN) and one low voltage (nn) with a connection system Yy, to which low voltage circuits (3) equipped with a capacitor dynamometer and a capacitor battery diode (4) are connected on the side of low voltage circuits star,so that the zero points of the condenser stars are connected to the zero point of the low voltage winding star by means of a neutral wire.
