In this paper, the authors focus on the study of the behavior, characteristics, causes and effects of arc faults in Low Voltage (LV) switchboard. A pressure sensor is designed to have an early detection on the fault by means of detecting the arc pressure. By monitoring the pressure of supply the current, the possibility of arc occurrence is minimized. From simulation results of the proposed circuit, the pressure sensor is able to detect an arc fault, send a signal to the fault protector circuit which in turn alerts the breaker control circuit to trip the appropriate circuit breaker, thus avoiding damages to the switchboard, buildings and personnel injury caused by arc flash.
