Critical Power: Know how to design power systems in mission critical facilities
1 AIA CES APPROVED LU AVAILABLE FOR ATTENDEES UPON SUCCESSFUL COMPLETION OF AN EXAM.
Mission critical facilities typically require electrical engineers to design and specify significant amounts of
power to increase reliability, limit outages and provide for redundancy. Common examples of mission critical facilities include hospitals, laboratories and data centers.
With the need for extensive power, these facilities often require the engineer to design medium–voltage primary services, primary service transformers, low–voltage distribution gear and uninterruptable power supplies. In some smaller mission critical facilities, the local utility may furnish primary medium–voltage equipment, leaving the engineer to focus on low–voltage systems design.
Learn about the choices and criteria for the planning and design of mission critical facility switchgear, automatic and static transfer switches and UPS.
- Understand NFPA 70B: Recommended Practice for Electrical Equipment Maintenance and the Uptime Institute’s Tier classification system for data centers.
- Determine options for mission critical switchgear, automatic and static transfer switches (ATS), and uninterruptible power supplies (UPS).
- Review common generator and UPS configurations to achieve N+1 and 2N redundancy.
- Consider various electrical system design examples by reducing single points of failure.
