3 phase motor current

1. whare are you now, because i dont know are you in which country,
if in Hong Kong the formula is follow
3 phase I = P / (V√3Cosφ)
= 15000 / (380*1.732*0.85)
= 15000 / 560 = 26.8A
if your country power supply is 3 phase 220V, you mush use this
= 15000 / (220*1.732*0.85)
= 15000 / 324 = 46.3A
if your country power supply is 3 phase 480V, you mush use this
= 15000 / (480*1.732*0.85)
= 15000 / 707 = 21.2A
