Transformer Tap Optimization determines and checks the transformer tap (turns ratio) so that the transformer is capable of delivering the max Mvar output and generator operating voltage variation ranges. The Mvar Delivery Curve provides the results of the Transformer Tap Optimization calculation in a graphical format. The plot depicts generator voltage vs. the generator reactive power output. This format is also called the generator reactive power (Mvar) delivery capability, because it shows the generator reactive power output range at the calculated transformer tap and system operating voltages.
