FIELD: electrical engineering. SUBSTANCE: device for protection of transformer connected to power line via isolating switch makes it possible to avoid hazardous current effects on power equipment with commutation of artificial two-phase short-circuits and deep drops of voltage in network causing intensive brake of synchronous motors at users and to provide for fast and selective localization of emergency connections. EFFECT: increased operational reliability of power line. 1 tbl, 4 dwg
