The required no-load ratio in a 1 -phase 50 Hz core type transformer is 6000/250 V. Find
the no. of turns in each winding if the flux is to be about 0.06 wbs.

Expert Answer:

Transformer equations for primary voltage Vp and secondary voltage Vs are given as
 
Vp = 4.44 × Np × f × Φ 
 
Vs = 4.44 × Ns × f × Φ
 
Where Np and Ns are number of primary and secondary windings , f is frequency and Φ is magnetic flux
 
Np = Vp / ( 4.44 × f × Φ ) = 6000 / ( 4.44 × 50 × 0.06 ) = 450 turns
 
Ns = Vs / ( 4.44 × f × Φ ) = 250 / ( 4.44 × 50 × 0.06 ) =  19 turns
