How does Shenzhen cable fault tester test high and low voltage cable fault tester manufacturers Today Shenzhen Noyafa will tell you how the cable fault tester tests high and low voltage! 1. First, judge whether the cable fault is high resistance or low resistance or grounding , According to how Shenzhen cable fault tester tests high and low voltage cable fault tester manufacturers Today Shenzhen Noyafa will tell you how the cable fault tester tests high and low voltage! 1. First, judge whether the cable fault is high resistance or low resistance or not is grounding, and different test methods are used according to this condition. The fault distance can be measured by the second or third pulse. Compared with the traditional test method, the advanced point of the second and third pulse method is to simplify the complex waveform in the shock high-voltage flashover method into a very simple low-voltage pulse short circuit. The fault waveform, so the interpretation is very simple, and the fault distance can be accurately calibrated. How does Shenzhen cable fault tester test high and low voltage 2. When finding a path, add a signal to the cable, then use the receiver to receive the signal, and walk along the path with the signal to determine the path of the cable.
3. Accurate positioning according to the measured distance. When you hear a very loud sound from the headphone of the pointing device, you have found the location of the fault point.
