How to Evaluate Percentage Regulation of Transformer?

Percentage Regulation of Transformer evaluator uses Percentage Regulation of Transformer = ((No Load Terminal Voltage-Full Load Terminal Voltage)/No Load Terminal Voltage)*100 to evaluate the Percentage Regulation of Transformer, The Percentage regulation of transformer formula is defined as The voltage regulation of the transformer, the percentage change in the output voltage from no-load to full-load. And since power factor is a determining factor in the secondary voltage, power factor influences voltage regulation. This means the voltage regulation of a transformer is a dynamic, load-dependent number. Percentage Regulation of Transformer is denoted by % symbol.

How to evaluate Percentage Regulation of Transformer using this online evaluator? To use this online evaluator for Percentage Regulation of Transformer, enter No Load Terminal Voltage (V_no-load) & Full Load Terminal Voltage (V_full-load) and hit the calculate button.
