Mine cable fault tester

Mine cables are not fundamentally different from other cables, but the environmental conditions under which the instruments are used are different, so there are different requirements for the instruments compared to other cables. For example, coal mine cables may not be tested using high-voltage flashover method, and some mines may not be convenient to use high-voltage instruments. Some of the mine cable fault testers on the market use pulse reflection method for direct testing, which can test for short circuit and broken wire faults; Some use the intelligent bridge testing principle for testing, which can test leakage high resistance faults with low resistance values at the fault point; Some use both pulse reflection method and bridge method, resulting in a wider range of applications.
Through the above introduction, we can see that although the types and names of instruments are different, the testing principles are actually just a few. The different names of instruments are mainly due to the manufacturer naming the instruments according to the needs of marketing according to the different users. As an instrument user, it is important to understand the testing principle used by the instrument, rather than its name, in order to determine whether it can meet the requirements.
