Class Description
Tap changer data.
Attributes
| Name | Type | Description |
|---|---|---|
| bil | Voltage | Basic Insulation Level (BIL) expressed as the impulse crest voltage of a nominal wave, typically 1.2 X 50 microsecond. This is a measure of the ability of the insulation to withstand very high voltage surges. |
| ctRating | CurrentFlow | Built-in current transformer primary rating. |
| ctRatio | Float | Built-in current transducer ratio. |
| frequency | Frequency | Frequency at which the ratings apply. |
| highStep | Integer | Highest possible tap step position, advance from neutral. |
| isTcul | Boolean | Whether this tap changer has under load tap changing capabilities. |
| lowStep | Integer | Lowest possible tap step position, retard from neutral. |
| neutralStep | Integer | The neutral tap step position for the winding. |
| neutralU | Voltage | Voltage at which the winding operates at the neutral tap setting. |
| ptRatio | Float | Built-in voltage transducer ratio. |
| ratedApparentPower | ApparentPower | Rated apparent power. |
| ratedCurrent | CurrentFlow | Rated current. |
| ratedVoltage | Voltage | Rated voltage. |
| stepPhaseIncrement | AngleDegrees | Phase shift per step position. |
| stepVoltageIncrement | PerCent | Tap step increment, in per cent of rated voltage, per step position. |
