Product Description

 

Product Introduction

The cable fault locator uses the acousto-magnetic synchronization method to determine the location of the cable fault point. The electronic flashover is generated by the impulse discharge generator, picked up and amplified by the corresponding probe, and judged by auditory and visual sense to determine the precise location of the fault point, complete the precise positioning of the cable fault point within the range of the cable fault point, it integrates acousto-magnetic time difference positioning technology, noise reduction technology, path-assisted testing and other technologies, and provides multiple test modes and rich and diverse prompt information to efficiently and accurately complete cable fault location.


This pointing instrument is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of various materials of different cross-sections and different media, such as power cables, high-frequency coaxial cables, street lamp cables, and buried wires, as well as high-resistance leakage and high-resistance flashover fault. The technical parameters comply with "GB/T 18268.1 Requirements for Immunity of Test Equipment for Industrial Sites".

It complies with the standard requirements for acousto-magnetic fixed point in the standard "DL T 849.2-2019 General technical conditions for special testers for electric power equipment Part 2: Cable fault pointing instruments". 


Main Function & Features

(1)Acousto-magnetic synchronous positioning technology is used to automatically calculate the acoustic-magnetic time difference, reducing the dependence on sound monitoring.
(2)The background noise reduction technology effectively filters out environmental interference noise and highlights the discharge sound at the fault location.
(3)Combining the traditional acoustic measurement method and the advanced acoustic magnetic method, the operator freely chooses according to the usage habits.
(4)The gain value and trigger value of the acoustic signal and magnetic signal can be adjusted manually, which is more convenient to fix the point.
(5)It has the function of path auxiliary indication to avoid offsetting the path when the point is fixed.
(6)Adjustable parameters, select appropriate filter parameters, and suppress environmental noise.
(7)7-inch touch highlight LCD to ensure visibility in the sun.
(8)Built-in  high-capacity lithium-ion battery power supply, with fast charger.
(9)Small and portable, light weight.
