A bar type current transformer of toroidal construction requires 400A to magnetize it, and 300 A to supply the iron loss for each volt per turn induced in the secondary winding and rated frequency. Across the secondary terminal is connected an impedance of 2 ohm with a phase angle . and the resistance of secondary winding is 0.5 ohm. The nominal ratio is 1000/5 A, and it is required to minimize both ratio and phase errors. Determine the necessary values of secondary winding turns and phase angle.
