Abstract
There is provided an apparatus for sensing an arc in a gas insulated switchgear (GIS) including: an optical signal receiving unit receiving an optical signal generated due to an arc within a GIS; and a circuit breaker controller outputting a circuit breaker interrupt signal based on the received optical signal, wherein the optical signal receiving unit is installed within the GIS. An optical signal due to an arc may be received at the maximum level, and an arc generated within a GIS may be simply sensed at low costs.
