RatioTapChanger
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. |
