SUMMARY
Differential protection for transformers effectively detects phase-to-phase faults by monitoring differential current, ensuring that the current entering a transformer equals the current exiting. However, it does not protect against turn-to-turn faults within a single winding, as these faults maintain a two-terminal topology, which the differential protection cannot identify. This limitation is crucial for understanding the scope of differential protection in transformer applications.
