Abstract

Every year, fires bring great loss and damage, and arc faults is one of main causes. But it is identified that the conventional circuit breakers fail to interrupt the circuit when an arc fault occurs. It is necessary to find new protecting techniques to improve the safety of circuits and reduce the probability of fires. This paper shows a simple method of detecting parallel arc faults. In this thesis, two significant characters of parallel arcs, the “shoulders” and the high amplitude, are obtained by experiments and then a circuit for discriminating the parallel arcs depending on them is designed. Other normal working household appliances, such as computers, air-conditions, are also have the similar characters, not easily distinguished from arc faults. The waveforms of those appliances are studied and compared with arcs. Results show that they still have different features in “shoulders” or amplitudes. At last, the correctness and reliability of this method are tested by an AFCI-tester.
