Question

A power transmission line feeds power at 2200 v with a current of 5 A to a step down transformer with its primary winding having 4000 turns calculate the number of turns and the current in the secondary in order to get output power at 220v

Open in App

Solution

V1 = 2200v
V2 = 220v
N1= 4000 turns
N2=?
Current I1=5A
Current I2=?

V1/V2 = N1/N2 = I2/I1

2200/220=4000/N2

N2= 400 turns

V1/V2 = I2/I1

2200/220 = I2/5

I2= 50A
