Abstract
This paper briefly introduces the frequent occurrence of electrical fires in China, analyzes in detail five failure modes in electrical fires, such as short circuit, poor heat dissipation, poor contact, overload and leakage, and analyzes the current main domestic electrical fire monitoring methods according to the failure modes. By studying the serious problem of false alarm in the process of residual current monitoring, the current follow-up technology is creatively developed, which effectively avoids the “false alarm” problem of electrical fire monitoring caused by the change of inherent leakage current.
