ROVPTOV has one analog group input which must be properly configured.
| Input | Description |
|---|---|
| URES | Residual voltage (measured or calculated) |
Note: See the preprocessing function blocks in this document for the possible signal sources.
There are a few special conditions which must be noted with the configuration.
| Condition | Description |
|---|---|
| URES calculated | The function requires that all three voltage channels are connected to calculate residual voltage. Setting VT connection must be "Wye" in that particular UTVTR. |
Improper analog channel configuration causes a validation error if the analog channels are not completely configured or they do not match with certain settings. For troubleshooting, check the contents of this chapter and also the preprocessing blocks in this document. The configuration can be written to the protection relay once the mismatch is corrected.
