 Some of the most important regulators in the grid affect the tap position of transformers.
 These {hoverxreftooltip}`user_manual/components:Transformer Tap Regulator`s try to regulate a control voltage $U_{\text{control}}$ such that it is within a specified voltage band.
 The $U_{\text{control}}$ may be compensated for the voltage drop during transport.
