摘要： An arc detector for detecting undesired arcs. The arc detector includes: an antenna for receiving an electromagnetic signal representing an arc; and a discriminator for analysing a signal from the antenna, the discriminator including a spectrum analyser arranged to detect whether the signal represents a normal arc or an undesired arc. The discriminator is arranged to detect whether the signal represents a normal arc or an undesired arc by comparing signal levels at frequencies of a spectrum of the signal corresponding to at least one partial reference spectrum, and determining the arc to be a normal arc if a deviation from the reference spectrum is less than a threshold deviation. A corresponding method is also presented.

摘要： A device for switching in and out a load with respect to an alternating voltage feeder has two mechanical switches connected in series in a current path between the load and the feeder and each having a by-pass branch with at least one member with ability to block current therethrough in at least a blocking direction and conduct current therethrough in at least one direction. A unit is adapted to control a procedure of a switching out and switching in by synchronization with the current in the feeder and the voltage of the feeder, respectively.
