ABSTRACT:
A toroidal shaped metallic housing, mounted on and electrically connected with a high voltage transmission line, is adapted with a metal plate and an intervening dielectric sheet adhered to its exterior surface. The housing, tied to the transmission line voltage, and the metal plate constitute the electrodes of a first capacitor of a capacitive voltage divider, while the capacitive coupling of the metallic plate with the surrounding environment provides a second voltage divider capacitor. The voltage appearing on the plate is processed by circuitry within the housing to derive a signal indicative of the transmission line voltage.
