1. Control system for magnetic comparator of alternating currents, comprising of three comparators and admittance current divider, characterised in that a marked clamp (ZP1) of primary winding (UP1) of the first comparator (K1) is connected with an unmarked clamp of the primary winding (UP2) of the second comparator (K2) and a measurement clamp (ZP2) of the primary winding (UP2) of the second comparator (K2) is connected with a marked clamp (ZP3) of the primary winding of the comparator (K3). Marked clamps (ZW1), (ZW2) and (ZW3) of secondary windings of comparators (K1, K2) and (K3) and marked clamps (ZK1, ZK2) and (ZK3) of compensatory windings of comparators (K1, K2 and K3) are joined together in a common point (W), whereas unmarked clamps of secondary windings of the comparators (K2 and K3) are connected with system's mass (M) through resistors (R), and unmarked clamps of compensatory windings of the comparators and an unmarked clamp of the secondary winding (UW1) of the comparator (K1) are connected directly to the system's mass (M).<IMAGE>
