A current transformer having primary turns of 2400 and secondary turns of 20 is connected to a source of 400 V and an impedance of 4410 n. A CT has a primary winding induced voltage of 390 V and a secondary impedance of 2425 N. Assume no load current of CT is zero. a) Draw equivalent circuit diagram in view of the above statement. b) Calculate burden of CT. Question No. 2: (5) Marks Explain with reason whether open circuit condition is dangerous for a current transformer or a short circuit condition? Question No. 3: (7) Marks A moving-iron instrument has dL = 702 mH with a full scale deflection of 90 degrees at 3 A. Estimate de 02 +1 A where 0 is the 4 the angular deflection of the pointer for a square of the current as 30 defelection in radians from zero position.
