Create one row for every protection, control, alarm and interlocking function. The matrix links the design intent to its final witnessed evidence.
Recommended columns
- Function ID and hazard or system requirement.
- Initiating quantity or state.
- CT/VT/LPIT source and polarity.
- IED function, setting group and logic equation.
- GOOSE/hardwired signal reference and supervision.
- Output contact, trip relay, coil and breaker.
- Expected alarm, indication, event and SCADA point.
- FAT test case, SAT test case, result and evidence link.
- Design owner, test owner, witness and approval status.
Minimum functional cases
- Intended operation at the protection boundary.
- Security for external or reverse faults.
- Loss of VT, CT, sensor, communications, time and DC supply.
- Local/remote and test/maintenance selector positions.
- Breaker failure, lockout, intertrip and autoreclose interaction.
- Alarm/event/SCADA mapping and timestamp quality.
Change control
Assign each row a settings, logic, drawing and SCL revision. A change to any dependency must identify which completed tests are invalidated and require repetition. Close the project only when every credited function has approved evidence or a formally accepted deviation.
