Street lamp cable fault tester

The essence of street lamp cable fault tester is to solve the problem of low-voltage cable testing. The testing methods can be divided into two types: step voltage method and electromagnetic wave fixed point method, which are suitable for testing street lamp cable faults, buried cable faults, buried cable to ground insulation faults, cross-linked cable outer sheath faults, buried line cable faults, and so on. In terms of its testing principle, it is actually the same as a direct buried cable fault tester.
