How is the reactive power compensation device connected to the high voltage line in the substation?
Transformer in substation generally has three windings, besides high voltage winding and low voltage winding, there will also be a compensation winding, which is generally connected by a star triangle! The line coming out of the compensation winding is connected with a switch, a reactor is connected in series (to suppress closing inrush current and harmonic), and then an isolating switch is connected (the general harmonic is 5,7, 1 1, so three isolating switches are connected in parallel), and a parallel (fuse protection) capacitor is installed at the bottom of the isolating switch! The general voltage of high voltage compensation is 10KV!
