Abstract
Selectivity of directional active power (‘wattmetric’) relays for zero sequence earth-fault protection of compensated medium voltage distribution networks is analysed. The analysis is based on estimation of zero sequence steady-state currents in compensated networks. Maloperations caused by imbalance currents of zero sequence current filters are taken into account. A new method to improve the selectivity is proposed.
