Product Description
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.
This XHDD503C cable fault locator is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flashover. Fault. The technical parameters comply with "GB/T 18268.1 Anti-interference requirements for test equipment used in industrial sites".
Features
1. 5-inch touch-high brightness LCD ensures visibility under sunlight.
2. Adopt acoustic and magnetic synchronous positioning technology to automatically calculate the acoustic and magnetic time difference.
3. The gain value and trigger value of the acoustic signal and magnetic signal can be manually adjusted to adapt to various environments.
4. It has background noise reduction technology and can choose from a variety of filtering methods.
5. It has BNR background noise reduction and mute noise reduction functions.
6. It has path deviation indication.
7. Equipped with multi-layer physical isolation signal sensors, waterproof grade IP65.
8. Built-in large-capacity lithium battery, long standby time, equipped with fast charger.
9. Small and lightweight, easy to operate, and simple human-machine interface.

Technical specification
Working principle
This device uses the acoustic and magnetic synchronization method to accurately locate faults. It is a very accurate and unique positioning method. Its principle is based on the traditional acoustic point determination method and adds the detection and application of electromagnetic signals.
When the high-voltage generator performs impact discharge on the faulty cable, the sound generated by the discharge at the fault point is transmitted to the ground. The sound signal is picked up by a high-sensitivity probe. After amplification, a "pop" sound can be heard by listening with headphones.
The built-in probe of the probe receives the magnetic field signal in real time, and uses the principle that the propagation speed of the magnetic field is much higher than the propagation speed of sound to determine the distance of the fault point by detecting the time difference between the electromagnetic signal and the sound signal. Keep moving the sensor position to find the point with the smallest acoustic-magnetic time difference, then the exact location of the fault point will be below it.
Traditional acoustic measurement legal point instruments generally only use earphones to monitor, or are supplemented by the swing of the meter pointer to identify the discharge sound at the fault point. Since the discharge sound disappears in an instant and is not much different from the ambient noise, it often brings great difficulties to operators who are not very experienced. The acoustic-magnetic synchronization method effectively avoids the above problems of the traditional acoustic measurement method.
