Abstract

More than 70% of the electric fire cases happen in this country are caused by arc. This paper aims to prepare measures of preventing electric fires resulted from arc by analyzing the technical standards and related regulations on the existing circuit breaker. Based on the study, we concluded that the technical and legal standards of the arc detector should be separately regulated from those of existing circuit breaker, considering the characteristics of arc detectors. Accordingly, we suggested in this paper that the arc detector related regulations should either be added to the existing circuit breaker related regulations, or to be handled separately. For effective prevention of electric fires caused by arc, it is urgently required to install arc detector and it is, therefore, appropriate to make it mandatory to install an arc detector. Under the given circumstance, it is suggested that the arc detector related regulations should be added to the existing regulations for the circuit breaker. The technical standards of arc detectors should reflect the arc judgement specification, breaking threshold of arc and the range of unnecessary signal that breaker should not react to respond.
