What is Voltage Regulation of Transformer?Voltage Regulation DefinitionVoltage regulation is a measure of the voltage change between no load and full load in electrical components, including transformers.Transformer Voltage DropWhen a transformer is loaded, the secondary terminal voltage drops due to impedance, causing a difference from the no-load voltage.Voltage Regulation FormulaThe voltage regulation of a transformer is calculated as a percentage using the formula involving load and impedanc
