Abstract
An apparatus and method for repelling animals, such as rodents and birds, from electrical power distribution equipment using voltages induced from inductive coupling with electromagnetic fields generated by said equipment is disclosed. Animals are repelled by non-lethal electrical shocks administered when the animal comes in contact with the system. An electrical potential above ground potential is induced and maintained on the system without the requirement of a direct electrical connection to an electric power source. The induced electrical potential discharges upon contact with an animal thereby producing a non-lethal electric shock that effectively discourages the animal from remaining in the area.
Claims8
An apparatus for repelling creatures, such as rodents and birds, from electrical power distribution equipment, said electrical power distribution equipment generating an electromagnetic field, said apparatus comprising:
- a bare electrical conductor mounted on said electrical power distribution equipment within said electromagnetic field and in electrically insulated spaced proximity to an electrically grounded conducting structure;
- said electrical conductor acquiring an electrical potential induced thereon by said electromagnetic field;
- whereby a creature coming into contact with both said electrical conductor and said grounded conducting structure completes an electrical circuit and is administered an electrical shock.
An installation for repelling animals, such as birds and rodents, from electrical power distribution equipment, said electrical power distribution equipment generating an electromagnetic field, said installation comprising:
- an electromagnetic field;
- an electrically grounded structure disposed within said electromagnetic field;
- electrically insulated means for supporting a bare electrical conductor in a substantially horizontal plane in proximally spaced relation with said electrically grounded structure, such that an electric potential in induced on said bare electrical conductor by said electromagnetic field;
- and
- whereby a creature coming into contact with both said electrical conductor and said grounded conducting structure completes an electrical circuit and is administered an electrical shock.
