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,
- Vno-load is the no-load voltage measured across the secondary terminals
- Vfull-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
