FIELD: electrical engineering.
SUBSTANCE: proposed device designed to meter amount of direct and reverse active and reactive power in high-voltage power transmission line or substation portals has insulator-mounted current transformer connected to transmission-line conductor suspended from crosspiece between insulators of given supporting structure or portal. Bushing insulator is connected in series with line conductor through its current-carrying component on section of its suspension on supporting structure insulators; current transformer is mounted on bushing insulator across the latter.
EFFECT: reduced time and facilitated procedure for device installation and wiring.
