<p>The present invention relates to a system for detecting arc and corona of a distribution board with a noise removal function based on an AE sensor. The system for detecting the arc and corona of the distribution board with the noise removal function based on the AE sensor includes a sensor unit which is installed in a housing of the distribution board and is composed of an acoustic emission (AE) sensor detecting the acoustic signal of the corona or arc and an acoustic generator which generates a reference acoustic signal, and a monitoring device which produces the generation position of the arc or corona. The monitoring device includes a signal processing unit, a reference sound generating unit, an arc detecting unit, a location analyzing unit, an abnormality determining unit, and a display alarm unit.</p> |
