Features:
1, the equipment adopts ultra-low frequency signal injection method, strong resistance to capacitance interference. Accurate positioning.
2, by injecting detection signals into the fault phase of the line, determine the single-phase grounding fault point, reduce blindness and shorten the fault detection time;
3, in the normal operation of the line, can detect the line load current.
4, single-phase grounding fault point error does not exceed 1 meter.
5, the device adopts Cortex-M3 core STM32 as the main control chip, high integration, strong anti-interference ability, fast running speed, low power consumption.
6, the operator away from high pressure, inspectors on the ground through the insulation rod operation, safe and reliable.
7, the device with internal power supply, no need to provide additional power, easy to use.
8, low power consumption, long use time.
