    Abstract

    This study-based paper describes the kind of short-circuits vs. the faulted networks that can produce short-drops in the voltage supplied to the Catalonia customers. Some experiences based on registered power-loss data during HV faults will be analyzed, along with the performance of the involved protective system (relays and breakers). An analytical method to calculate short-drops as a function of network short-circuit parameters is developed for MV radial networks. Finally, experience-based impacts for faults in HV systems and statistics of faults in the different HV faults in Catalonia are presented.
