The smart electricity safety management system uses the self-developed residual current transformers, temperature sensors and electrical fire detectors through the safe use of electricity to handle the main factors of electrical fire (cable temperature, current, voltage and leakage current). Uninterrupted data tracking and statistical analysis, real-time discovery of electrical hazards in electrical circuits and electrical equipment (such as cable temperature abnormality, short circuit, overload, overvoltage, undervoltage and leakage), effectively avoiding electrical fires .
