ABSTRACT:
The present disclosure provides a wildlife guard for electrical power equipment including a disc having a central opening for fitting onto the equipment. The disc includes an electrically insulating material with a conductive filler material in quantity sufficient for the disc to maintain an electrostatic charge. The disc has an insertion slot extending from an outer portion to the central opening for movement of the disc onto the equipment. The present disclosure also provides a wildlife guard for an electrical insulator bushing having an electrical conductor extending outwardly therefrom. The wildlife guard includes an electrically nonconductive cover for covering at least a portion of the electrical conductor, the cover being adapted to mount upon the bushing and a conductive panel attached to the cover.
