Abstract
Based on the relationship between electrical equipment discharge and ultraviolet radiation, this paper proposed the use of UV pulse method to detect switchgear arcing faults. Switchgear protection system based on this new technique detects arcing faults by analyzing the ultraviolet produced by electric arc. The technique was implemented and tested in laboratory, and results verified the performance of the protection system; its capable to calculate the number of UV pulses and cut off faults fast and precisely.
