High voltage side current calculation: 80Kva * 0.058A / Kva = 4.64A 1000Kva * 0.058A / Kva = 58A
Low voltage side current calculation: 80Kva * 1.444A /Kva = 115.52A 1000Kva * 1.444A / Kva = 1444A /Kva=115.52A 1000Kva*1.444A/Kva=1444A
The above is only used for the calculation of high and low voltage current of 10Kv voltage level
