成果简介	NOVELTY - The relay has a current sensor located on a transformer device, which is provided with a short-circuited winding (17) for converting a single-phase electrical signal into a six-phase. An input circuit is provided with separate primary windings (4). The first primary winding is connected to an input terminal (1). The second primary winding is connected to an end of the first primary winding. An end of the second primary winding is connected to the input terminal. A filter output is connected to an input of a comparison circuit (22). An actuator (23) is connected to an output of the comparison circuit. USE - Current relay for used in electrical circuits of relay protection and automation of medium and low voltage power systems based on transformer device. ADVANTAGE - The relay increases speed and accuracy of relay protection response in emergency modes. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit diagram of a current relay. 1Input terminal 4Primary windings 17Short-circuited winding 22Comparison circuit 23Actuator
