METHOD FOR DISCONNECTION OF A SWITCHGEAR OF A TRANSFORMER SUBSTATION AND FOR SIGNALING AND INFORMING PERSONNEL OF AN ELECTRIC GRID ORGANIZATION AT UNAUTHORIZED SUPPLY OF VOLTAGE FROM A LOW SIDE OF A TRANSFORMER SUBSTATION

摘要

FIELD: electrical engineering.;SUBSTANCE: invention relates to electrical engineering, in particular to methods of disconnecting switching devices of transformer substation. Result is achieved due to disconnection of switching device from low side of transformer substation, as well as signaling and informing personnel of electric grid organization on unauthorized supply of voltage from low side of transformer substation, developing situation, at which, due to voltage supplied unauthorized to the network from the low side of the transformer substation and by means of its transformation at the transformer substation supplied to the high side of the transformer substation and, accordingly, to the power transmission line on the high side, people may be under stress.;EFFECT: technical result consists in improvement of safety of electrical networks servicing.;1 cl, 1 dwg
