Answer:
The input voltage of the step-down transformer is 26.945 kV
Explanation:
Given:
R = 2.35 Ω
I = 650 A
Vs = 10 V
Vp = 1 V
Vs/Vp = 10/1 = 10
Vp = 3 kV
Vs = 10*Vp = 3*10 = 30 kV
The input voltage of the step-down is:
V = Vs - 2IR = 30000 - (2 * 650 * 2.35) = 26945 V = 26.945 kV
The input voltage of the step-down is [tex]26.945kV[/tex]
It is a static device which step up and step down the voltage at same frequency.
Given that,
The input voltage of the step-down is,
[tex]V = V_{s} - 2IR = 30000 - (2 * 650 * 2.35) = 26945 V = 26.945 kV[/tex]
