FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to methods of power supply to consumers, and can be used for power supply to consumers through transformers with higher voltage of 6–110 kV. Prior to switching on the electric installation switch in parallel, each safety fuse is replaced with a spare fuse with disconnector disconnected. Use of spare fuses with disconnectors makes it possible to provide uninterrupted power supply to consumers at blasting of one or several working safety locks of power transformer, by means of which transformer is connected to supply buses.
EFFECT: technical result consists in provision of uninterrupted power supply to consumers in case of blown fuses of power transformer, by means of which transformer is connected to supply buses.
