100kVA transformer can withstand much of the current? What is its formula?
For safety insurance, the current density is about 3.0, S = 144.34 / 3 = 50 (about)
So take the 50 square cable can be.

Three-phase transformer: rated capacity S = √3 * rated voltage U (line voltage) * rated current I (line current)
On the subject: S = 100KVA
High pressure U1 = 10 KV I1 = S / (√3 * U1) = 5.77 A
Low pressure U2 = 0.4 KV I2 = S / (√3 * U2) = 144.34 A
