| Abstract |
Arcs caused by a variety of electrical factors at the site of the electrical industry cause fire and explosion accidents. It is difficult to protect safety with existing MCB(Main Circuit Breaker) and fuses used in industrial sites from these arcs. Current and harmonic analysis methods used in existing arc detection methods have a problem that it is difficult to identify arcs under some nonlinear loads, such as Thyristors used in dimming lamps. In addition, Background noise is generated in the AC system due to noise from the peripheral device and biological noise. This background noise generates RF power in areas below 20MHz. Therefore, in this paper, we extract and amplify high-frequency noise components in areas outside the interference of background noise when the arc occurs, and convert them into a Received Signal Strength Indicator (RSSI) voltage to detect serial arcs for resistance loads and thyristor loads. |
