Therefore,






















               Regulation




















               Example 6.16   A 440/220 V single-phase transformer has percentage
               resistance drop and reactance drop of 1.2 per cent and 6 per cent,
               respectively. Calculate the voltage regulation of the transformer at 0.8 power

               factor lagging.


               Solution:



               Percentage voltage regulation
