摘要：A system is disclosed for transmitting alternating current power and
communication signals between a first location and a second location via a communicationpath which includes at least one inductive load (5) and at least one switching means (13)for switching power to said at least one load on and off. The system includes controlmeans (25) adapted for controlling said at least one switching means so that, in responseto switching off said power, a direct current is applied to said at least one inductive loadand, in response to actuation of said at least one switching means to switch said poweron, said power is switched on during a phase of the power which results in a
magnetisation of said at least one inductive load opposite to that resulting from saiddirect current.
