Example 32.14. A single phase transformer takes 10 A on no load at p.f. of 0.2 lagging. The turns ratio is 4: 1 (step down). If the load on the secondary is 200 A at a p.f. of 0.85 lagging. Find the primary current and power factor. Neglect the voltage-drop in the winding. (Nagpur University November 1999) Example 32.14.
