Zusammenfassung:	FIELD: power engineering, possible use for compensating for deviations of three-phased load voltage and reactive network power. ^ SUBSTANCE: device contains two one-phased frequency transformers, one of which has constant current unit (three-phased to one-phased) and another one has direct connection and natural commutation (one-phased to three-phased). Between them a high frequency reducing transformer is coupled. Input of frequency transformer with constant current unit is connected to load, and output of frequency transformer with direct connection is coupled in the splitting of star of secondary winding of three-phased power transformer of substation. Also, device composition includes filter-compensating device and battery of cosine capacitors with total generated reactive power equal to 50% of reactive power of substation. ^ EFFECT: twice reduced installed capacity of transformer-gating regulating device, improved harmonic composition of output voltage and speed of operation. ^ 3 dwg
