Can you explain why you multiply 166.7 × 3 ?

[@EngHanyKamel]

Power ofeach phase 166.7MVA, so 3 phases total power 166.7X3

[@EngHanyKamel]

You can also calculate by Square root (3) X rated line voltage X rated line current

[@EngHanyKamel]

Or calculate by 3 X rated phase voltage X rated phase current
