The Transformer Having Less Regulation And Therefore More Or Less Constant Secondary Terminal Voltage Is Always Considered As A Good Transformer.

Generally, a transformer is utilized to supply loads that operate at basically constant voltage. The transformer by its very nature induces voltage into the secondary which is proportional to that supplied at the primary depending on the turns ratio. Voltage regulation depends on the voltage drop in the impedance of the transformer, load current and load power factor.
