Figure 4. Equivalent Circuit, TDR Traces showing Fault Location Pinpointing Before digging in order to repair the faulted cable, some type of pinpointing technique must be used. The classical methods ...

On comparison, power devices, especially IGBTs, can withstand short-circuit current only for very short time durations in the order of microseconds and prolonged exposure can easily damage the power ...

In the process of practical application, coaxial cable is prone to soft faults such as wear. In this paper, the influence of faulty cable on impedance spectrum is analyzed by using the transmission ...
