Course Description
Power system protection is very important for utilities and industrial electrical distribution networks, because it limits the damage in electrical networks caused by short circuit and other type of faults. The course contains the different types of relays, the function of each relay, the basic requirements of the protective relays and how to protect the electrical network components such as transformers, generators, motors, feeders, distribution and bus-bars.
