Apparatus for monitoring voltage on a high voltage overhead transmission line
This patent describes an apparatus for monitoring voltage on a high voltage aerial transmission line comprising, in combination: A. an electrically conductive housing removably mounted on a high voltage aerial transmission line; B. means electrically connecting the housing to the transmission line whereby the housing assumes the electrical potential of the transmission line; C. a dielectric sheet adhered to the exterior surface of the housing; D. a metallic plate adhered in overlying relation to the exposed surface of the sheet, whereby the housing and the plate constitute the electrodes of a first capacitor and the capacitive coupling of the plate with the surrounding environment constitutes a second capacitor connected with the first capacitor as a capacitive voltage divider; E. circuitry situated within the housing responsive to the voltage appearing on the plate for developing an output signal indicative of the transmission line voltage; and F. a lead connected with the plate and admitted through an opening in the housing for connection with the circuitry situated within the housing.
