Restricted Earth Fault protection in Dyn Transformers

Restricted earth fault protection for a transformer with neutral connection Figure 2 shows and example where three phase current CTs are connected parallel with …...
Restricted earth fault protection is often applied even when the neutral is solidly earthed. Since fault current then remains at a high value even to the last turn of the winding (Figure 4), virtually complete cover for earth faults is obtained.
