FIELD: electricity.
SUBSTANCE: from the moment of occurrence of operating current surge with a value determined with load of a tripped section of the line of the main power source, time reckoning is started, which is equal to delay time of switch-on of a sectional switch of the same line, and if operating current in the line of the main power source is increased by the value determined with load of the standby section, and decreased in the line of the standby power source by the same value from the end moment of reckoning of the same time to the moment of trip of the automatic load transfer network station switch, a conclusion is made on trip of the automatic load transfer network station switch and restoration of normal electric power supply circuit of the ring network. When applying the proposed method, information can be received on trip of automatic load transfer network station switch at restoration of normal electric power supply circuit of the ring network.
EFFECT: enlarging functional capabilities.
