    calculate transformer impedance

    How to find transformer impedance ( Delta- Y grounded transformer 12000V - 480V)?First , I calculate I2 using this formula -->I2= KVA(load)/Volt_left_side. After that, I calculate I1 using the formula , N1/N2 = I2/I1. After that , I calculate Z2 = V2/I2. Next , I calculate Z1 using this...
