The low-voltage pulse method of the cable instrument host tests the length of the cable, and the radio wave transmission speed of the proof cable is tested. The full length of the cable can let us know more about the specific situation of the faulty cable, and can judge whether it is a high-resistance or low-resistance fault, and can judge the inherent radio wave speed. The low-voltage pulse method of the host to test the length of the cable, check the radio wave transmission speed of the cable, and test the full length of the cable, so that we can better understand the specific situation of the faulty cable, judge whether it is a high-resistance or low-resistance fault, and judge whether the inherent radio speed is accurate (accurate The transmission speed of the radio wave is the guarantee to improve the test accuracy. When the speed is inaccurate, the speed can be inversely calculated.).
These can be solved with the low voltage pulse test method.
