| This paper presents a novel auto-reclosing blocking method for distribution lines that have transitions from overhead to underground cable in distribution systems solidly or impedance grounded with distribution transformers in delta connection in their high voltage sides. The main contribution of this new technique is that it can detect if a ground fault has been produced at the overhead line side or at the cable line side improving the performance of the auto-reclosing functionality. This localization technique is based on the measurements and analysis of the argument differences between the load currents in the active conductors of the cable and the currents in the shields at the cable end where the transformers in delta connection are installed, including a Wavelet analysis of such argument differences. This technique has been checked through computer simulations and experimental laboratory tests. | |
