Voltage regulation of Transmission line:
- When a transmission line is carrying a current, there is a voltage drop in the line due to the resistance and inductance of the transmission line.
- Finally, the receiving end voltage ( VR ) of the line is generally less than the sending end voltage (VS)
- The difference in voltage at the receiving end of the transmission line between the conditions of no-load and the full load is called voltage regulation
- Voltage regulation is expressed as a percentage of the receiving end voltage.
