Abstract: A unique electrical system includes a first electrical component and a second electrical component. A conductor electrically couples the first electrical component with the second electrical component. A sensor is constructed to sense an AC power flow in the conductor and output an AC signal proportional to the AC power flow. A band-pass filter is in electrical communication with the sensor and constructed to receive and filter the AC signal and to generate an AC voltage proportional on the AC signal. A controller is in electrical communication with the band-pass filter, and is operative to receive and sample the AC voltage. The controller is configured to execute program instructions to sum sequential AC voltage values received from the band-pass filter over a sample time period, and to determine whether an arc fault has occurred based on the summed AC voltage values.

Abstract: A device is provided. The device may include a first electrical connector, a second electrical connector, an interconnect, and a magnetic field detector. The interconnect is mounted in electrical contact with the first electrical connector and the second electrical connector and includes a loop. The magnetic field detector is located in proximity to the loop of the interconnect. The magnetic field detector is located to detect a current flowing in the interconnect when the current flows in the interconnect.
