Transformer Circuit








Formulas

To compute the number of primary and secondary turns:

\[ N_1 = \frac{V_1}{\text{Voltage per Turn}} \]

\[ N_2 = \frac{V_2}{\text{Voltage per Turn}} \]

To compute the full-load currents:

\[ I_1 = \frac{\text{VA}}{V_1} \]

\[ I_2 = \frac{\text{VA}}{V_2} \]

Example Calculation

Let's assume the following values:

Step 1: Compute the number of primary and secondary turns:

\[ N_1 = \frac{2500}{2.5} = 1000 \text{ turns} \]

\[ N_2 = \frac{250}{2.5} = 100 \text{ turns} \]

Step 2: Compute the full-load currents:

\[ I_1 = \frac{25000}{2500} = 10 \text{ A} \]

\[ I_2 = \frac{25000}{250} = 100 \text{ A} \]
