A system and method for feeder protection in an electrical power network nodal point including at least three feeders. In the system and the method it is executed in an intelligent electronic device reserved for the feeder, on the basis of the at least one measured electrical quantity actual in the respective feeder, at least one first protection function monitoring a power system related condition of the respective feeder, as well as in a central intelligent electronic device, for at least one feeder, at least one second protection function monitoring the same power system related condition of the feeder. Furthermore the central intelligent electronic device is configured to further execute for the at least one feeder, on the basis of the at least one measured electrical quantity actual in the other feeders connected to the same nodal point, at least one third protection function monitoring the same power system related condition of the feeder.
