-0 marks
A three-phase delta-wye connected 30MVA, 33 kV/11 kV transformers is protected by a simple differential relaying scheme. The CT ratio on the primary side is 500: 5 and that on the secondary side is 2000: 5. Sketch the CT connection diagram for the relaying scheme. Also calculate the relay current setting for faults drawing upto 200% of the rated current.
