Decoded

Reports grid overfrequency, grid underfrequency, grid frequency out of range; confirm with grid frequency measurement; do: utility company consultation, grid settings check.

What can be behind Grid overfrequency

Failure modes that present as the reported condition, and the tests that tell them apart.

What can be behind Grid underfrequency

Failure modes that present as the reported condition, and the tests that tell them apart.

What can be behind Grid frequency out of range

Failure modes that present as the reported condition, and the tests that tell them apart.
