Definition

Voltage regulation of a transformer can be defined as the change in the magnitude of the secondary voltage of a transformer when the load changes from full load to no-load, assuming a constant primary voltage.

Where,

• V_no-load is the no-load voltage measured across the secondary terminals
• V_full-load is the voltage measured across the secondary terminal at full load.

Per cent voltage regulation

Normally, voltage regulation is expressed as either per – unit or percentage of load voltage
