Did your protection system operate when it shouldn't have — or fail to operate when it should? Misoperations are more than an operational headache: for NERC registered entities they can trigger PRC-004 investigation and reporting obligations with firm deadlines.
NERX investigates unexpected operations end to end: event record and relay target analysis, settings review, root-cause determination, and corrective action planning. Where PRC-004 applies, we prepare the documentation needed to fulfill the requirement.
