A tap changer is a mechanism in transformers which allows for variable turn ratios to be selected in distinct steps. This is done by connecting to a number of access points known as taps along either the primary or secondary winding. Tap changers exist in two primary types, no-load tap changers (NLTC), which must be de-energized before the turn ratio is adjusted, and on-load tap change… WebTransformer Tap circuits: That is used to increase or decrease the output voltage of the transformer, the taping mention in number and they have some percentage of the voltage ratio, typically 0.1 to 5 percentage.
