Zusammenfassung:	FIELD: electrical engineering; reactive power correction in power lines. SUBSTANCE: saturable reactor has two-yoke magnetic system with two side legs and intermediate legs carrying control windings connected to converter or to dc power supply. Power winding of each phase is placed on two intermediate legs carrying differentially connected control windings. Average diameter DPW and radial size aPW of power winding in each phase, effective cross-sectional SCW area H of magnetic-system intermediate legs, rated voltage U and power Q of one phase of saturable reactor are interrelated by expression , where SPW = pi(DPW+aPW/3)2/4- is effective cross-sectional area of power winding in each phase; f is supply frequency; mu0 = 4pi.10-7 H/m is magnetic constant; w is power winding turn number in each phase. EFFECT: reduced material input and loss; improved form of current curve. 1 cl, 4 dwg
