Arc faults are a fire-safety risk in both AC (alternating current) and DC wiring. Still, reliable detection of arc faults and determining the appropriate response is incredibly tricky in DC plug-load circuits. This study will discuss the impact of impedance on arc interference characteristics in DC low voltage systems. Experiments were conducted involving accidents that increasingly occur using the arc chamber as a means of experimenting with independent variables, including cross-sectional cable area and the number of fibers and control variables will consist of currents and voltages using devices using a Picoscope. The following are the results of testing the effect of channel impedance on the Arc Error on the current value and peak power generated at 29.75 A and 45.826 W. Whereas the value of the increase and heat energy is 0.01 s and 0.454 Ws.
