Percent loss constants method settings
| Parameter | Values | Description |
|---|---|---|
| Meter Information | ||
| Rated Meter Voltage | Numeric |
The nominal meter input voltage. Use this value to calculate the iron loss constants. The rated meter voltage is the line-to-neutral voltage for three-element metering or the line-to-line voltage for two-element metering. |
| 1/2 Meter Current | Numeric |
Half of the certified meter class current. Use this value to calculate the loss constants. |
| Number of Stator Elements | Integer | The number of measurement elements used in the meter. Delta systems use two stator elements and Wye systems use three. |
| Instrument Transformer Information | ||
| Potential Transformer (PT) Ratio | Numeric | The instrument transformer's primary to secondary voltage rating ratio. |
| Current Transformer (CT) Ratio | Numeric | The instrument transformer's primary to secondary current rating ratio. |
| Iron Loss Compensation | ||
| Compensate Iron Loss | Off, On |
Turns iron loss compensation off or on:
|
| Percent Iron Watt Loss (%LWFe) | Numeric | The percent of active power lost due to iron (core losses). |
| Percent Iron VAR Loss (%LVFe) | Numeric | The percent of reactive power lost due to iron (core losses). |
| Copper Loss Compensation | ||
| Compensate Copper Loss | Off, On |
Turns copper loss compensation off or on:
|
| Percent Copper Watt Loss (%LWCu) | Numeric | The percent of active power lost due to copper (winding losses). |
| Percent Copper VAR Loss (%LVCu) | Numeric | The percent of active power lost due to copper (winding losses). |
