Anordning för seriekompensering av elektrisk växelströmsmaskin

摘要

The method involves connecting a capacitive circuit (14) for the fundamental frequency of the voltage is in each phase between the down side of the winding and the earth point (20) of the distribution or transmission network (6). Each capacitive circuit includes a capacitor. An over-voltage protection device (26) is connected in parallel with the capacitors. A band-stop filter (16) is arranged between the Y-point of the capacitor bank formed by the capacitors and the earth point of the distribution or transmission network. A low Ohmic resistor is connected between the band-stop filter and the earth point. The windings are wound using high-voltage cable.
