Abstract :
This paper describes the development of a multisensor device, based on four different physical phenomena, for reliable detection of low-level arcing faults in metal-clad switchgear. The proposed device was tested for actual arcing, generated on a low-voltage motor control center panel, feeding a dry type 15 kVA, 230/115 V Y/Δ transformer. Some results showing the performance of the developed device are presented in the paper. The device can also be applied for detection of arcing in power electronic drives, dry type transformers, gas insulated switchgear, generator bus-ducts, and other metal-clad electrical apparatus
