Transformer calculation 5

 Question = एक 2200/200 volt transformer no Load पर 0.6 ampere current  और 400 watt power ले रहा है । Magnetizing तथा iron loss current मालूम करें ?

Solution = is given , 

Primary voltage (EP) = 2200 volt ,  secondary voltage (ES) = 200 volt , No Load current (IO) = 0.6 ampere ,  Power (p) = 400 watt ,  

magnetizing current (Iμ) = ? , Iron loss current (Iw) = ? , 

» formula = Iw = IO × Cos Ø ,  

» Cos Ø = W ÷ (VP × IO)  » 400 ÷ 2200 × 0.6 , 

» 0.3 , 

» Cos Ø = 0.3 , तो sin Ø = √1- cos ز

»  sin Ø= √1-0.3²  » 0.953 

» Iμ = IO × sin Ø ,  » 06 × 0.953  » 0.572 , ampere answer ✓

» Iw = IO × Cos Ø , » 0.6 × 0.3 » 0.18 ampere , answer ✓
