FIELD: electricity.
SUBSTANCE: amplitude of signal current introduced to phases BC of 0.4 kV line to be compared in prototype and in the proposed method is the same and is equal to Im=17A. The result is achieved by the fact that to the proposed generator containing 10/0.4 kV transformer the low-voltage windings of which are connected to input of double-wave rectifier bridge (bridge), resistor the second output of which is connected to the first input of controlled key, the first, the second capacitors, there introduced is air inductance coil the first output of which is connected to output of controlled key and the first armature of the second capacitor, the second armature of which is connected to phase B of 0.4 kV line, the second output of air inductance coil is connected to negative bus of bridge and to the first armature of the first capacitor, the second armature of which is connected to phase C of 0.4 kV line, and positive bus of bridge is connected to the first output of resistor.
EFFECT: consumption of power is reduced by 2,8 times without using air transformer.
