  • Detection of potential on high-voltage transmission lines
    Patent number: 3991367
    Abstract: A suspension insulator used on the tower of a high-voltage transmission line has a capacitive voltage dividing pickup plate placed thereon to capacitively pick up a low-power indication of the potential carried by the line. In order to detect the potential on the plate, the potential difference between the plate and the tower is limited, rectified and applied to a neon lamp in a photo coupler. A photosensitive element in the photo coupler responds to the light from the lamp to operate a relay to control remote indicators.
