The maximum fault current in a given circuit is 12 000 A. The nominal CT ratio is 1200/5 and the CT is to be used with a tap of 800/5. The CT class is C-200, the resistance of the secondary is 0.2 02, the total secondary load is 2.4 and the power factor is 0.6. Determine if, on the occurrence of a fault, the error will exceed 10%.
