Introduction

This Power System Protection training course covers the fundamentals of protecting a power system against hazards posed by abnormal system conditions, such as short-circuit faults. An overview of the protective devices available for application, both industrial and utility, is presented along with typical means of implementing these devices. Both electromechanical and digital relays are discussed. Fuse selection and coordination is explored in depth. Utility-specific protective devices, such as reclosers and sectionalizers, are presented, and utility-specific protection strategies, such as fuse-saving and fuse-blowing are covered. This Power System Protection training course allows the delegates to apply techniques learned in this course to realistic protection scenarios.
