ABSTRACT:
An insulation housing has a central opening to allow the housing to be mounted on a high voltage conductor. A continuous, circular cylindrical electrode band is embedded within the housing and is capacitively coupled to a conductor which passes through the central opening of the housing. The electrode may be the sole electrical component encapsulated within the housing. The lead from the electrode is then coupled to indicators which are fixed on remotely positioned switchgear cubicles. The indicators include neon glow bulbs and a solid state relay which are operated by the energy derived from the capacitive pickup structure.
