- Protect synchronous generators against configured electrical faults.
- Maintain an installed SIPROTEC 3 protection panel during a legacy-system overhaul.
- Execute coordinated breaker tripping from measured generator quantities.
- Protection elements operate from the engineered current and voltage inputs.
- Trip outputs follow the configured matrix and enabled setting group.
- Coordination settings must remain consistent with the generator protection study.
- Measured values and event records support post-fault assessment.
- Front-panel indications expose pickup, trip and device states.
- Time alignment is required when correlating the relay record with plant events.
- Use only the relay variant approved for the switchgear and plant jurisdiction.
- Commissioning records should demonstrate the required protection test coverage.
- Panel modifications must preserve applicable insulation and wiring practices.
