What is Voltage Regulation of Transformer?

Voltage Regulation Definition

Voltage regulation is a measure of the voltage change between no load and full load in electrical components, including transformers.

Transformer Voltage Drop

When a transformer is loaded, the secondary terminal voltage drops due to impedance, causing a difference from the no-load voltage.

Voltage Regulation Formula

The voltage regulation of a transformer is calculated as a percentage using the formula involving load and impedance.

Lagging Power Factor Impact

With a lagging power factor, the current lags behind the voltage, affecting the voltage regulation of the transformer.

Leading Power Factor Impact

With a leading power factor, the current leads the voltage, also impacting the transformer’s voltage regulation.
