Abstract :
The first part of this paper contains a short review on single phase to earth fault location methods in compensated networks. After that a new fault location method is presented that has been implemented recently at Hungarian DSOs. This technique uses current injection parallel to the Petersen coil, and the same device is further used to decrease the harmonics in the residual fault current during sustained earth-fault operation. First field test results are also shown.
