FIELD: electric engineering. SUBSTANCE: method involves calculation of ratio of full power of substation to power of main power supplies that total current causes switch of fast-response relay to supply line division for de-energizing of short-circuit current from faulted substation connection. EFFECT: simplified precise leading division of supply line when unsafe short-circuit currents at substation switches are detected. 1 dwg
