Beschreibung
Zusammenfassung:	The present invention relates to a device which detects an ultraviolet range (180-270 nm) of an arc generated inside a distribution board by using an optical fiber with a focusing lens attached thereto or a sensor module, determines whether the arc is generated based on calculation, and outputs an arc generation signal to respective outputs for channels, a composite output (alarm), and an RS485 communications port, such that notification, alarm, and fire extinguishing devices are operated and a comprehensive monitoring system associated with electric relays is established. The present invention is also related to a light arc device for the distribution board capable of controlling sensitivity for respective channels characterized by having a plurality of sensing channels for simultaneously monitoring multiple arc generation sources; and setting arc detection sensitivities for respective channels such that the sensitivities are set with respect to monitoring sites inside the distribution board. Therefore, measuring sites with fine sensitivity (high sensitivity) and low sensitivity are efficiently monitored at the same time.
