Question

Calculate the primary voltage of a transformer with a turns ratio of 1 : 2 and a secondary voltage of 960 V.

Answer 1

Given:

Turns ratio `(N_p/N_s) = 1/2`

Secondary voltage (V_s) = 960 V

Formula:

`V_p/V_s = N_p/N_s`

`V_p/960 = 1/2`

`V_p = 1/2 xx 960`

V_p = 480 V

The primary voltage of the transformer is 480 V.
