Class Description

A tap changer that changes the voltage ratio impacting the voltage magnitude but not the phase angle across the transformer.

Angle sign convention (general): Positive value indicates a positive phase shift from the winding where the tap is located to the other winding (for a two-winding transformer).

Attributes

Name Type Description
stepVoltageIncrement PerCent Tap step increment, in per cent of rated voltage of the power transformer end, per step position.
When the increment is negative, the voltage decreases when the tap step increases.
