Abstract
Abstract A plug and receptacle combination is transformer coupled. There are no exed contacts to the environment at any time, whether the plug and receptacle combination are mated or separated from each other. By encapsulating the primary winding and secondary winding separately in a respective plug and receptacle, mating and unmating can be accomplished while submerged in water.
