“…In the Chinese market, there has been a significant increase in the availability of arc fault detection products designed to identify and prevent arc faults occurring in residential properties. There have been many researchers conducting standard and additional tests on AFDDs in the Chinese market [6][7]. The arc fault detection products primarily rely on algorithms that distinguish between fault current and normal current.…”

There are two sets of standards available in the Chinese market that specify the design requirements and operating tests for arc fault detection devices (GB/T 31143) and arcing fault detectors (GB 14287.4) respectively. While arcing fault detectors (AFDs) are claimed to have passed GB 14287.4 standard tests, it remains unclear whether these AFDs can pass GB/T 31143 standards and effectively detect arc fault signals. This study experiments to explore the operational performance of AFDs in the Chinese market based on GB/T 31143 standards, revealing that not all AFDs can pass this test and provide adequate protection for people’s lives and property. The main reason for the failure is that the arcing characteristics, such as flat shoulders and reduced amplitude, of the signal are easily masked by other branch circuit loads.
