KDJK-10A can only locate the fault after the fault occurs, and the fault is reproduced by applying high voltage to the fault line from the transmitter. The ultra-low frequency current flows from the transmitter to the fault point, enters the earth through the transition resistance and flows back to the transmitter. Along the line, sensors are connected to the line through insulated rods to detect the current.

1, use: 6-35kV overhead line small current grounding fault search and positioning.
2. Application scenario: The line stops operation after a ground fault occurs.
3, transmitter high voltage, high power, stable current, can measure high resistance fault.
4, ultra-low frequency signal to overcome the impact of system distribution capacitance, high resistance fault location.
5, highly sensitive opening sensor, no need to close, convenient line connection.
6, sensor-receiver wireless communication, safe and reliable.
7, numerical value/waveform display, the criterion is clear and intuitive.

1, positioning accuracy: 0.1m
2, transmitter output characteristics: 1Hz, 0~8kV, 0~100mA, 1000W(max)
3, measurable line length: ≥100km
4. Wireless communication distance between sensor and receiver: >100m
