Voltage regulation:

Voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a transmission or distribution line. The ideal voltage regulation is 0%. It should be as low as possible

\(V.R = \frac{{({V_{NL}} - {V_{FL}})}}{{{V_{FL}}}}\)

VNL = No load voltage

VFL = Full load voltage

V.R = Voltage regulation
