2. Cable fault pinpoint locator (XHDD503C)
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 fixed-point instrument 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.
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.
