OVERVIEW
Relay settings, time-current coordination, selectivity checks, breaker coordination, and protection philosophy for grid-connected and islanded systems.
Protection decisions
- Which faults and operating modes must the system safely clear?
- Are relay settings selective with upstream and downstream devices?
- What protection evidence is needed for utility or owner approval?
Compliance outputs
- Protection philosophy and setting assumptions
- Fault-level and coordination review notes
- Grid-code, relay, or safety compliance matrix
- Utility-ready technical documentation
