Power Protection
Overview
Power protection ensures system stability during outages, surges, and electrical inconsistencies.
This includes UPS systems, surge protection layers, and runtime planning to maintain continuous operation.
🎯 Scope
- UPS sizing and load planning
- Surge protection (layered approach)
- Runtime strategy and shutdown planning
🧠 Key Concepts
- Power instability can cause system failures, data corruption, and hardware damage
- UPS systems provide both backup power and power conditioning
- Surge protection should be layered (service entrance + device level)
- Runtime must align with actual shutdown or continuity requirements
System Design
UPS Sizing
- Calculate total load (watts, not just VA)
- Include headroom (20–30%)
- Account for startup surge if applicable
Surge Protection
- Whole-building surge protection (primary layer)
- Rack or device-level protection (secondary layer)
- Protect network, cameras, and server hardware
Runtime Strategy
- Short runtime → graceful shutdown
- Medium runtime → ride-through outages
- Long runtime → generator integration
⚠️ Common Mistakes
- Undersizing UPS capacity
- Ignoring total system load
- No surge protection at service entrance
- Assuming UPS = surge protection (it is not enough alone)
- Not testing runtime under real load
