This paper investigates whether existing protection schemes would detect an open phase fault in the power supply systems of a 1092 MW Spanish nuclear power generating station. This investigation follows to the 2012 event at unit 2 of Byron station, Illinois, USA. Symmetrical components method is proposed to draw fundamental conclusions. The results of the symmetrical components analysis are validated using EMTP simulations.
