Introduction
The cable fault location instrument uses the acoustic and magnetic synchronization method to determine the power cable fault point. The electronic flashover is generated by the impact discharge generator, picked up and amplified by the corresponding probe, and the precise location of the fault point is determined by auditory and visual judgment. It is a device that completes the precise positioning of the cable fault point within the rough measurement range and collects the acoustic and magnetic time difference. It integrates positioning technology, path-assisted testing and other technologies, providing multiple test modes and rich and diverse prompt information to efficiently and accurately complete cable fault location.

XHGX507C

Introduction

XHGX507C is a path detection instrument with strong comprehensive performance.
It has multiple functions such as pipeline path detection, cable identification, fault finding, etc. The instrument consists of a transmitter, a transmitting current clamp,a receiver, a receiving flexible current clamp, a connecting test line, and an A-frame (optional).

 Technical specification

 

Function	Pipeline detection (cable position tracking, direction display, depth measurement, current measurement), cable identification, A-frame fault finding (optional function)
Power	8.4V large capacity rechargeable lithium battery
Input method	Built-in receiving coil, flexible caliper, A-frame (optional function)
Receiving frequency	Active detection frequency: 640Hz, 1.28kHz, 2.56kHz, 3.20kHz, 4.09kHz, 8.19kHz, 10.2kHz, 32.7kHz, 65.6kHz, 81.9kHz, 197kHz Power frequency passive detection frequency: 50Hz, 60Hz, 250Hz RF passive detection frequency band: center frequency is divided into 32.7kHz, 65.6kHz, 81.9kHz, 197kHz
Pipeline detection mode	Broad peak method, narrow peak method, valley method
Pipeline detection Detection range	Direct connection method: Generally, the cable length can reach 0~20 km, which is mainly determined by the ground resistance, cable resistance and cable buried depth Coupling method: Generally, the cable length can reach 0~10 km, which is mainly determined by the ground resistance, cable resistance and cable buried depth Induction method: Applicable to cables buried less than 2m deep
Depth and Current	Real-time display of cable depth and current value
Pipeline measurement depth	0-20m
Depth Accuracy	Plane position precision: Center axis position of target cable or pipeline: ±5% (buried depth 0-3m) -10% (buried depth 3m-20m)
True or False Tips	Eliminate interference from adjacent cables. When measuring adjacent cables, the measurement of adjacent cables can be distinguished based on the different signal strengths and measured current phases fed back by the adjacent cables. In the process of tracing the cables, observe the phase dial and pointer pointing to distinguish the measured cable from the adjacent cables.
Sound Instructions	FM tone that varies with signal strength
Anti-interference display	Green: No interference Green: Good (results can be trusted) Red: Severe interference (results cannot be trusted)
Anti-interference ability	The extremely narrow receiving frequency band and unique digital processing method can fully suppress the power frequency and harmonic interference of nearby running cables and pipelines.
Interference distance	When using the coupling method and the induction method, the transmitter will generate interference within a short distance. The interference distance is related to the transmission power and frequency. The greater the power and the higher the frequency, the stronger the interference. The minimum distance at which the receiver is not interfered by the transmitter often needs to be determined by experiment: Pipeline detection: 5m away for the coupling method and 20m away for the induction method can be confirmed as no interference Cable identification: 2~5m away for the coupling method can be confirmed as no interference
Cable identification	Identification method: Intelligent identification by flexible clamps; Number of cables that can be calibrated: 1 to 20; Calibration value: The current percentage of the receiving signal and the transmitting signal is between 75% and 135% of the calibration value, which is one of the conditions for successful identification; Directionality: The transmitting clamp, the receiving clamp and the loading signal must be in the same direction, which is one of the conditions for successful identification.
Cable identification Detection range	Direct connection method: can identify signals with a loop resistance of 0Ω to 8kΩ (usually can reach a cable length of 0 to 20 kilometers, mainly determined by the ground resistance and cable resistance) Coupling method: can identify signals with a loop resistance of 0Ω to 1kΩ; (usually can reach a cable length of 0 to 6 kilometers, mainly determined by the ground resistance and cable resistance)
