Fault Diagnosis in Transmission Lines: Trends and Main Research Areas

Fault diagnosis in transmission lines constitutes a problem in power systems with relevant technical and economic impact for independent system operators and also for the asset owner itself. Several techniques have been proposed in the literature to deal with this problem in a significant number of applications. This survey presents the main research areas and the trends in transmission line fault diagnosis in power systems. Classification of strategies and their relationship with applications are shown and discussed.
