要約(英語): Partial disconnection of element conductors in AC power cords of household electric appliances or in extension cords is a major cause of fire accidents originating from electric equipment. This kind of disconnection usually occurs in cords that have suffered from mechanical stress. Safety devices based on a reliable method for detecting the disconnection of element conductors have a great potential for preventing accidental fires. In this study, a series of laboratory experiments are carried out using a 100-V AC power cord, where 49 out of 50 element conductors are cut artificially. The temperature of the intact element conductor rises due to Joule heating and is finally disconnected by arc discharge. A fire-prevention device that responds to the anomaly in the voltage waveform observed during arc discharge could be designed.
