Abstract
The influence of the fault place grounding impedance in algorithms for ground faults distance relay is not usually taken into account. The fault place grounding impedance depends on design characteristics of the ground wire and towers footing resistance. This paper shows a possibility of taking into account the fault place grounding impedance in the algorithm for the ground fault distance relay. The algorithm taking into consideration the fault place grounding impedance has better accuracy and only slightly greater complexity.
