Document Type and Number:
WIPO Patent Application WO/2012/085495
Kind Code:
A3
Abstract:
An electrical power and/or electrical signal transmission system for transmitting electrical power and/or electrical signals from a location on a first side of a metallic wall to a location on a second side of the metallic wall. The system comprises transmitting apparatus (4) comprising an electrical source (51) and a first transformer (61). The electrical source (51) is electrically connected to a primary winding (61a) of the first transformer and first and second ends of a secondary winding (61b) of the first transformer is electrically connected to respective spaced locations on the first side of the metallic wall for applying electrical power and/or electrical signals to the metallic wall. The system also comprises receiving apparatus (3) comprising a receiving module (34) for receiving electrical power and/or electrical signals and a second transformer (31). First and second ends of a primary winding (31a) of the second transformer are electrically connected to respective spaced locations on the second, opposite, side of the metallic wall for picking up electrical power and/or electrical signals from the metallic wall. The receiving module (34) is electrically connected to a secondary winding (3b) of the second transformer to enable electrical power and/or electrical signals to be transmitted from the electrical source to the receiving module.
