About this document
Power Transformer Protection Overview by brightmore is a document available to read on EtoBox.
This document discusses power transformer protection. It begins by stating that transformers are protected by a main protection device and backup protection to quickly disconnect them during faults. Approximately 70% of transformer failures are due to winding and tap changer issues. The damage from a transformer fault is proportional to the fault time, so protective relays are used to rapidly clear faults. Common protection schemes include differential protection, overcurrent protection, and restricted eart
