The formula to calculate Voltage Regulation in a Transmission Line is:
\[ \%V = \left( \frac{V_s - V_r}{V_r} \right) \times 100 \]
Voltage Regulation in a short transmission line refers to the ability of the line to maintain consistent voltage levels at the load despite fluctuations in source voltage or load impedance. Sending End Voltage is the voltage at the sending end of a short transmission line. Receiving End Voltage is the voltage developed at the receiving end of a short transmission line.
Let's assume the following values:
Using the formula:
\[ \%V = \left( \frac{400 - 380}{380} \right) \times 100 \approx 5.26315789473684\% \]
The Voltage Regulation is approximately 5.26315789473684%.
