Cable Fault Pinpoint Digital Power Cable Fault Locator PinpointerI. Introduction HZ-B
overhead line grounding fault locator, apply for small current grounding system overhead lines. The device can be used to precise position the docking site when the lines occur ingle-phase ground fault outage. II. Functional Characteristics
1. Suit for small current grounding system distribution network, detection for single-phase metallic ground, the arcing ground, the transition resistance grounding and other faults for overhead line.
2. After the line outage, the fault line can be located, especially for the cable branch of the fault line.
3. The high voltage signal is applied so that to reproduce the fault, the current signal is stable, easy to detect.
4. Avoid ultra-low frequency signal distributed capacitance system, capable of high resistance fault locate.
5. Transmitter safety features: high-voltage start lockout, output allows direct short circuit.
6. The sensor uses a high-sensitivity sensor, open design, without closure, easy to mount on the line.
7. The sensor and receiver for wireless communication transmission, safe and reliable.
8. The transmitter may use electricity, power generators, sensors and battery-powered receivers.
9. The transmitter small size, light weight; sensors to minimize volume and weight design, easy to mount along; receiver for handheld design.
10. The receiver employs large-screen LCD display, showing the status of the sensor, the current waveform and the current value. III. Technical Indicators
