The objective of this course is to review the types of faults that can occur in transformers and to present the different protection schemes that are installed on large and small transformers. After study of this course and the associated workbook, participants should be able to understand the following overall concepts and apply them to their day-to-day work activities. They will also be able to answer related test questions on these subjects: Transformer features, Types of faults, Overcurrent protection, Backup coordination, Primary fuses, Differential protection, In-rush current: harmonic filter, Phasing of differential CTs, Selecting CT taps, Calculation of mismatch, Differential protection for multi-winding transformers, Connection of multiple restraint coils, Limitations due to parallel CTs, Single-phase transformer CT connections, Ground (zero-sequence) protection, Directional ground protection, Remote transfer tripping, Thermal relays, Gas pressure relays, Transformer overall protection schemes, Protection of transformers in parallel, Reactor protection, Shunt capacitor protection.
