WebbTo select the most appropriate ATS, the overcurrent protection devices should be known and the results of a completed selective coordination study should be available. At that point, the information needed to select an ATS includes (1) the nominal voltage and amperage of the load, (2) the maximum fault current that will be available, and (3) the … WebbThis purpose can be achieved by proper coordination of protective devices. One of the aims of this thesis was to make a general guideline from which proper coordination of transmission system protection can be developed in Bhutan network. This thesis proposes a review of coordination of distance relays for transmission lines of a real
