Today’s LiveWire Spotlight looks at the second version of PRC-024-3, the modified NERC standard governing generator frequency and voltage protection settings, and the way they react to transients during a Disturbance. In the latest draft the Standards Development Team has made a large number of somewhat minor clarifications in response to stakeholder feedback on the initial draft – which received a 52.28% approval rating; fourteen points short the target.

The second draft of PRC-024-3 and its supporting materials have been posted for a 45-day review period and concurrent ballot. Clients have until November 4, 2019 to provide their comments back to the drafting team and place their ballots.
