In Chap. 7, it was shown that the two-terminal method using a coaxial wave velocity with arrival instances extracted in the time domain is a good strategy for a fault locator system for crossbonded cables. However, the cable models implemented in sim

Is was shown in Chap. 4 that an impedance-based fault location method is not practically applicable for hybrid lines due to the very different fault loop impedances of these two system types. In this section, methods based on travelling waves are dis

Over the last years, the Wavelet transform (WLT) has gained a lot of attention for solving fault location problems on transmission lines [1, 2, 3, 4, 5, 6, 7]. A fault locator system which do not require skilled personal to operate it is preferable a
