Question: The working principle of the low-voltage pulse measurement method Answer: During the test, a low-voltage pulse is added to the faulty phase of the cable, and the pulse propagates along the cable until the impedance mismatches, such as intermediate joints, T-joints, short-circuit points, open-circuit points and terminations Head wait, in this question: The working principle of the low-voltage pulse measurement method Answer: During the test, add a low-voltage pulse to the faulty phase of the cable, and the pulse propagates along the cable until the impedance mismatches, such as intermediate joints, T-joints, short-circuit points , break points and terminations, etc., at these points will cause the reflection of the electric wave, and the reflected pulse will be received by the tracer when it returns to the test end of the cable. The tracker can display this change in time.
