Today’s LiveWire Spotlight evaluates the latest posting of PRC-027-1 – which addresses the coordinated derivation/verification of relay settings to ensure that they operate in the proper sequence during a Fault. The project team has expanded the scope from earlier drafts to include Protection Systems located fully within a single owner’s footprint – not just those crossing entity boundaries.

The latest drafts of PRC-027-1 and its support documentation have been posted for a 45 day informal review period. Clients have until May 15, 2015 to return comments on the materials posted by the project team and to vote on the standards.
