Summary: | 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 analyzing a signal from the antenna, the discriminator including a spectrum analyzer 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. |
