FIELD: electrical engineering. SUBSTANCE: placed in each phase of device is resistor connected between voltage transformer primary winding and supply circuit. Device has also circuit connected in parallel with resistor and including transformer whose primary winding is connected to secondary winding, and fuse connected in parallel with secondary winding. Fuse has metal contact rod one end of which is laid on top of fusible link wire and other end is hinge-connected and connected to supply circuit. EFFECT: reduced weight and overall dimensions of transformer, increased efficiency of operation, reduced errors. 1 dwg
