1. A device comprising:
a core comprising at least two parts, said two parts being operative to close said core around an electric conductor passing there through; a coil of electric wire wrapped around at least one part of said core, said coil comprising two terminals, each at one end of said coil; and a switch, electrically coupled to said two terminals, said switch being operative to provide a short circuit of said coil upon demand; wherein mounting said device on said electric conductor comprises closing said two parts of said core around said electric conductor while said switch is open; and wherein demounting said device from said electric conductor comprises closing said switch to enable said two parts of said core to disengage from each other. |
