Introduction: The laying environment of power cable is extremely complex, and the precise location of cable fault is the most critical in the whole fault testing process. In today's technical conditions, the fault location of power cable has a better solution, but no matter how accurate the location, due to laying reasons and environmental impact, can only determine a approximate range, can not be accurately fixed, resulting in high labor intensity, blindness, low efficiency. To sum up, our company has developed the XSN-TC-04 cable fault precise fixed-point instrument, which integrates discharge acoustic wave display, fault distance digital display, high anti-interference and high sensitivity.
Product features:
1. Based on the method of acoustic magnetic signal transfer time difference, two modes of acoustic magnetic synchronous fixed point and step voltage fixed point are set;
2, the combination of high-performance digital filter circuit and low noise design, acoustic magnetic synchronization and step voltage two methods of comparison and verification, can ensure the accuracy and efficiency of fixed point;
3, at the same time, according to the limitations of the environment, choose multiple ways to test;
4, with sound closure function and intuitive man-machine interface;
5, ultra high anti-interference ability and a variety of filtering frequency band, for all kinds of cable fault can be accurate and quickly fixed.
