ABSTRACT:
A compact voltage sensing device for connection to an alternating current high voltage circuit is imbedded within an organic polymeric insulator body that is formed to provide both mechanism support and "line to ground" insulation for a conductor or component connected thereto. The voltage sensing device comprises a capacitor and step-down transformer in series from the conductor to ground which provides a low voltage output which may be used to determine the magnitude of the voltage on the conductor, or as a source of control voltage for auxiliary apparatus. The insulator body may be made to be equal in height and have the same mounting configuration as a conventional insulator so that it can be substituted for a conventional insulator in a distribution system. The performance of the insulator body as insulation is not compromised by the presence of internal electrical components.
