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.

Rectifier vs Power Transformer: Key Differences
Differences Between Rectifier Transformers and Power TransformersRectifier transformers and power transformers both belong to the transformer family, but they differ fundamentally in application and functional characteristics. The transformers commonly seen on utility poles are typically power transformers, while those supplying electrolytic cells or electroplating equipment in factories are usually rectifier transformers. Understanding their differences requires examining three aspects: working
