Enhanced Locating Method for Cable Fault Using Wiener Filter

Time domain reflectometry (TDR) has been widely used for detecting the fault location and fault type of power cable due to the low computational load and good adaptability. However, it is vulnerable in the cable characteristic, such as delay and attenuation fluctuating with frequency. In this paper, we execute the channel estimation using Wiener filter to compute the most similar estimated signal with the injected reference signal, and provide experimental results to show the performance improvement of fault detection and location using TDR with Wiener filter in power cable.
