Research on the Detection of Parallel Arc Faults Based on the Characteristic Analysis in Time Domain

Abstract

Arc fault is one of main cause of fires which bring great loss and damage every year. Researchers show that the conventional circuit breakers probably fail to interrupt the circuit when an arc fault occurs. So, it is very important and necessary to find a new way to detect the arc fault. This thesis focuses on discussing the special characters of parallel arc faults, which are the main cause of fires. In this paper, not only the data of parallel faults, but also the normal working data of different apparatus are obtained. Two significant characters will be described and they will be the key criterions to detect the appearance of parallel arc faults. At last, we test the correctness of this method and get good results.
