FIELD: measuring equipment engineering, in particular, equipment for measuring electric energy.
SUBSTANCE: to achieve result, on each core of appropriate current transformer compensating winding serially connected to working load resistance is wound, which is connected to input of adjuster, connected to secondary winding, so, that magnetic flow in core is practically zero, and voltage at resistor of working load is received in measuring module for determining load current.
EFFECT: improved precision of measurements.
