PRC-025-2: Generator Relay Loadability
PRC-025-2 exists to prevent unnecessary generator tripping during stable system conditions — protective relay settings must allow generators to operate up to their verified capability limits without mis-operation. It's often treated as a documentation exercise. It isn't.
The manual reality
- Capability data drift — generator capability curves and facility ratings change, but relay settings often go unreviewed
- Engineering silos — protection settings, facility ratings, and capability data living in different systems or teams
- Margin assumptions — settings that technically “pass” while latent risk builds unnoticed
- Audit reconstruction — rebuilding analysis after the fact instead of demonstrating continuous validation
What data phleet automates
- Ingests generator capability and rating data directly
- Evaluates load-responsive relay settings against PRC-025-2 criteria
- Flags non-compliant or margin-risk conditions automatically
- Tracks changes historically and maintains defensible documentation without manual intervention
