Abstract

Arc Fault is an electric discharge which is occurred in two opposite electrode. In this paper, AFCI(arc fault circuit interrupter) is designed for the interruption of arc fault current which is occurred in the local electric network. This arc is one of the main causes of electric fire. Arc fault in electrical network has the characteristics of low current, high impedance and high frequency. Conventional interrupter does not have the arc current interrupt function. Hence, Arc fault circuit interrupter controller is designed for the interruption of arc fault current which has the modified arc characteristics.
