Consider a 600:5 turn ratio CT of the class 10C400. a) Draw CT equivalent circuit. b) Calculate the estimated maximum secondary voltage of CT across the magnetizing branch at the maximum error when fault current is 5000 A at the primary. For the calculation assume that impedance of magnetizing branch is constant. c) What will be the maximum burden impedance (including leakage impedance) for CT at the calculated voltage at part a)? For the calculation of burden current assume magnetizing current and CT secondary current are in phase.
