Voltage regulation in a transformer is defined as the change in secondary voltage from no-load to full-load condition, expressed as a percentage of full-load voltage. To calculate this accurately, the applied (primary) voltage must remain constant so that any voltage variation observed is solely due to load and internal impedance effects.
Voltage Regulation Formula:
\(\text{Voltage Regulation} = \frac{V_{no-load} - V_{full-load}}{V_{full-load}} \times 100\%\)
To isolate the effect of load, the primary voltage must be held steady.
