摘要:
The invention deals with an AC power supply unit that reduces voltage for electric power equipment applicable in power distribution systems. The inventive device comprises at least one capacitor (2) which is connected into a transmission line (7) and which is connected in series with the grounded primary winding (5) of a transformer (3) whose secondary winding (6) is connected with the terminals of a protective device (8) connected into the receiver circuit (9) of the power system.
