- How to solve this using kirchhoff's law?☹arrow_forward2. (a) (b) (1) A 100 kVA, 4000 V / 200 V, 50 Hz single-phase transformer has 100 secondary turns. Determine: The primary and secondary currents. The number of primary turns. Three single-phase transformers are connected in Delta- Wye (A-Y) as shown in Figure 2.1. Each transformer is rated 100 kVA, 2300/13800 V RMS, 50 Hz. The total three-phase load L is 270 kVA with a power factor of 0.866 lagging. The input voltages are: VAB = 23000° VBC = 2300 Z-120° VCA = 2300 120° Assume that the transformers are ideal and the line-to- neutral voltage on the secondary are in phase with the input voltages.
