AC three phase Motor calculation part 9
Question = एक motor 4000 volt , 3 phase, 50 c/s AC Supply पर लगी हुई हैं । Motor 0.8 Cos Ø पर 25 ampere current ले रही हैं । Motor की input Kw तथा hp में मालूम करें ?
Solution = is given ,
VL = 4000 v , Cos Ø = 0.8 , I = 25 A , Input = ?
» input = √3 × VL × IL × cos Ø watt ,
» input = 1.732 × 4000 × 25 × 0.8 , = 138560 watt , या 138560 ÷ 1000 = 138.56 KW , answer ✓
» for HP = Watt ÷ 746 , = 138560 ÷ 746 , = 185.73 HP, answer ✓
