WebLoad Tap Changing Transformers. LTC transformers have tap ratios that can be varied to regulate bus voltages ; The typical range of variation is ?10 from the nominal values, usually in 33 discrete steps (0.0625 per step). Because tap changing is a mechanical process, LTC transformers usually have a 30 second deadband to avoid repeated changes. WebControl of transformer’s tap changer is the most popular form of voltage control at all voltage levels in a power system. This is based on changing the turns ratio of a transformer, hence the voltage in the secondary circuit is varied and voltage control is obtained. The tap changer is usually placed on the high voltage winding as the current ...
