Voltage Regulation Calculator

Calculate the percentage voltage regulation of a power system.

Voltages

No-Load Voltage (Vnl) (V)

Full-Load Voltage (Vfl) (V)

Regulation %

Overview

Voltage regulation is a measure of the change in voltage magnitude between the sending and receiving ends of a component, such as a transmission line or transformer.

💡

Pro Tips

Formula: VR% = ((Vnl - Vfl) / Vfl) * 100
Vnl: No-load voltage (voltage when no current is drawn).
Vfl: Full-load voltage (voltage under rated load).
Lower percentage indicates better regulation (stable voltage).

Fun Facts

"Ideal voltage regulation is 0%, meaning the voltage doesn't drop at all under load."
"Transformers and generators are rated by their voltage regulation capability."
"Automatic Voltage Regulators (AVR) are used to maintain constant voltage levels."

Formula: %VR = ( (Vnl - Vfl) / Vfl ) × 100
