Leakage Current Detector and Warning System Integrated with Electric Meter

Electrical power is essential in human life. Thus, the security and reliability of its supply are critical importance a country’s industrial economic development. The leakage improper use electricity may cause serious problems such as fire electrocution. To prevent incidents minimize loss life property, current detector warning system developed this study. With high-precision transformer high-gain linear converter, effectively detects over 1 mA, which validated different methods. can be integrated into widely used electric meters (Taipower Datong’s sub-meter model D4S) easily, information on detected transmitted to cloud server through narrowband IoT wireless communication (NB-IoT) warn users management personnel electrical line. proposed expected caused by was main at homes buildings an effective means manage powerline metering facilities.
