The paper deals with the issue of utilization faulty phase earthing (FPE) technique as alternative to single fault autoreclosing in resistor earthed medium voltage distribution network. Possible integration this common protection concept well current limitation efficiency is discussed paper. In order evaluate benefits flowing from FPE utilization, a sensitivity analysis simple network was performed focused mainly on impact dips and swells invoked at low level.
