SPD Coordination Verification Report Template

The SPD Coordination Verification Report Template is a standardized engineering document used to systematically validate and document the coordinated operation of multiple Surge Protective Devices (SPDs) in a cascaded protection scheme. It ensures that upstream and downstream SPDs exhibit appropriate voltage protection levels (Up), current handling capabilities (In, Imax), and energy coordination (e.g., let-through energy matching) to prevent destructive follow-current or thermal overstress during surge events. The template supports compliance with IEC 61643-12, IEEE C62.22, and national electrical codes.
