Protection for Distribution Substation Transformers Course (PC6)


We look at faults on distribution substation transformers and how they dictate protection settings, as well as how we deal with transformer inrush and pickup current. We show how to select a primary fuse to protect the station transformer and how to coordinate with upstream and downstream devices. Finally, we’ll look at the complete protection scheme for a real-world substation.
