FIELD: electricity.
SUBSTANCE: at the switched on condition of input busbar cut-out switches, at sections connected to a sectionalising switch occurrence of equalising current is controlled, and if it appears at the above sections simultaneously, then a conclusion is made about false tripping by the bus sectionalising switch of the double-transformer substation at the operation of a ring network as per the normal power supply scheme. The suggested method allows receiving data on false tripping by the bus sectionalising switch of the double-transformer substation at the operation of the ring network as per the normal power supply scheme.
EFFECT: reduction of energy consumption by the exclusion of a sounding method, by control of equalising current at the sections of busbars adjoining the sectionalising switch.
