■ Product Overview
The laying environment of power cable is very complicated, and the precise location of cable fault is the most important in the whole fault testing process. In today's technical conditions, the fault location of power cable has been better
Solution, but no matter how accurate the ranging, due to laying reasons and environmental impact, can only determine a roughly range, can not be accurately fixed, resulting in labor intensity, blindness, low efficiency.
To sum up, our company has developed the product XSN-2089 series cable fault precise fixed point instrument which integrates discharge acoustic wave display, fault distance digital display, high anti-interference and high sensitivity.
Based on the time difference method of acoustic magnetic signal transmission, this series of products set up two modes of acoustic magnetic synchronous fixed point and step voltage fixed point, and adopt the combination of high performance digital filter circuit and low noise design
Step voltage and step voltage are compared and verified to ensure the accuracy and efficiency of fixed point. At the same time, according to the limitations of the environment, choose multiple ways to test, with closed sound function and intuitive
Man-machine interface, ultra-high anti-interference ability and a variety of filtering bands, can accurately and quickly fix all kinds of cable faults.
