Problems solved by technology

[0005] Although the conventional AFCI detects the occurrence of an arc fault as described above and disconnects the power distribution system from the power source when an arc fault is detected, the conventional AFCI may not be able to detect the correct location (load) where an arc fault has occurred
Even when a conventional AFCI has detected the occurrence of an arc fault, the conventional AFCI may not be able to properly address (e.g., repair) the arc fault since the conventional AFCI may not be able to correctly determine where the arc fault has occurred

Embodiment Construction

[0036] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout.

[0037]figure 1 is a control block diagram of an electronic device according to an embodiment of the present disclosure.

[0038] Such as figure 1 As shown in , an electronic device 100 according to an embodiment of the present disclosure includes an electromagnetic interference (EMI) filter 110, an arc fault circuit interrupter (AFCI) (or arc fault detection device) 120, a wiring harness 130, a plurality (n) of loads 140 to 170 , a controller 180 and a display unit 190 .

[0039] The EMI filter 110 removes high frequency noise from alternating current (AC) power input to the EMI filter 110 and outputs the AC voltage or current from which the high frequency noise has been removed.

[0040] AFCI 120 includes a microcomputer 122 including memory 124 for determining whether an...

Abstract

An electric device includes a plurality of loads and an arc fault detection device to output arc signal detection information when an arc signal has been input from a wire harness connected to the plurality of loads. A method includes sequentially supplying, when the arc signal detection information has been input from the arc fault detection device, Alternating Current (AC) power to each of the plurality of loads during a preset time, and detecting a load at which an arc fault has occurred from among the plurality of loads. Thus, a location (load) at which an arc fault has occurred is correctly detected, thereby appropriately coping with (repairing) the arc fault.

Description

technical field [0001] Embodiments of the present disclosure relate to an electronic device and an electronic device system capable of detecting an arc fault causing an electrical fire and a method for detecting an arc fault in the electronic device, the electronic device system. Background technique [0002] Arc faults occur in electrical wiring due to aging, damage or insulation defects of the wiring, or physical / electrical stress on the wiring due to overcurrent. Because such arc faults cause electrical fires, the use of Arc Fault Circuit Interrupters (AFCIs) has become mandatory in the United States, where the AFCI is used to detect arc faults in electronic devices and disconnect the electronic devices when an arc fault has occurred circuit. [0003] The AFCI is installed on the distribution board to detect whether an arc fault has occurred on the distribution line, and to interrupt the power supply to the distribution line when an arc fault has been detected. [0004]...
