Transformer calculation part 7
Question = singal phase transformer का transformation ratio 1000/100 volt हैं , primary के turn 200 हैं । Secondary turn मालूम करें ?
Solution = is given ,
Es = 100 volt , EP = 1000 volt , NP = 200 ,
NS = ?
Formula = trans.. ratio = ES / EP = NS / NP ,
» 100 / 1000 = NS / 200 ,
» NS = (100 × 200) ÷ 1000 ,
» 20 turns, answer ✓
