Transformer Tap Changing Working Principle
Tap changing in Transformers It is a normal fact that increase in load lead to decrease in the supply voltage. Hence the voltage supplied by the transformer to the load
What is a Transformer Tap Changer
A tap changer is a device fitted to power transformers for regulation of the output voltage to required levels. This is normally achieved by changing the ratios of the transformers
