Abstract: The present invention provides an arcing detection method and system, in which an AI model derives an AI score from current data and preliminarily determines whether a current signal of interest is arcing based on a comparison between the AI score and an AI threshold. It preliminarily determines whether the determination is false. These two determination steps enable more accurate arcing detection. When a false determination count becomes greater than or equal to a false determination count threshold, the AI model is retrained and dynamically updated to adapt itself to the current situation. This dispenses with the need for deployment of multiple static AI models in the system, which requires larger storage memory. The AI model can adapt itself to the current situation without needing manual commissioning of parameters, effectively reducing manpower costs. Further, this dispenses with the need for regular interrogation of environmental changes, reducing the system's task overhead.
