Q4. A three-phase, 400 V/1Z kV Y-D connected transformer is protected by differential protection [4+2] scheme. The CTs on the LV side have a current ratio of 1000/5. (a) What must be the ratio of CTs on the HV side? (b) How should they be connected? Assume, Z is equal to the last non-zero digit of your student ID.
