To address the low efficiency of low-voltage leakage location

this paper develops a fault location device for upstream tripping caused by low-voltage leakage

which is specifically designed to prevent frequent power outages caused by leakage in meter boxes. By integrating low-voltage AC magnetic power tapping connectors

multiple voltage and current monitoring units

intelligent algorithms

and a micro application system

the device realizes accurate monitoring and rapid location of leakage faults. It features convenient installation

safe operation

continuous data acquisition

and fast response

thereby accelerating fault reporting and repair response and improving customer satisfaction. The device has significant technical advantages and practical value.
