Power protection

This research investigates the relationship between post fault transient overvoltages and the functionality of the digital distance protection. The study is conducted in a 66kV network with a neutral earth resistor as method to earth the power system. This paper begins by performing an extensive power system analysis on ground fault transient overvoltages. The study is conducted by using the PSCAD-EMTC software package.
