Description |
|---|---|
|
smpSynch |
Synchronization accuracy for all channels in the SMV frame. 0: less than 4 µs synchronization accuracy 1: synchronized to local clock within 4 us accuracy 2: synchronized to global clock within 4 us accuracy |
|
test bit |
The sender IED is in test mode. |
|
invalid 01 & bad reference |
The sender time synchronization is uninitial- ized (accuracy unknown). The sender has time accuracy less than 100 ms. |
|
invalid 01 |
The channel is not available. |
|
questionable 11 & inaccurate |
The accuracy of the measurement value is in- accurate or not supported. |
|
derived |
The channel is derived from other channels, for example, calculated residual voltage. |
