What are electrical and power systems?
Electrical and power systems are key to any nonresidential building type, and are designed by an electrical engineer. Depending on the building and its occupants’ needs, it may include backup, emergency and standby power systems. Other systems that come into play are wiring and cabling, switchgear, uninterruptible power supplies and fuses and breakers. Electrical engineers who design these systems must understand harmonic mitigation, electrical safety, smart grids and the various codes and standards that define them.
The Sept. 20, 2018, “Critical power: Arc flash mitigation” webcast presenters addressed questions not covered during the live event.
Electrical engineers must consider many factors when designing power-generation systems. Safety, maintainability, efficiency, code compliance, and economics play crucial roles in determining the topology of a power-generation system. Specific requirements for power vary based on building occupancy type, facility use, and critical function.
The electrical engineer is responsible for designing power distribution systems for buildings. Understanding the full circuit-protection requirements will enable the engineer to design the safest and most reliable electrical distribution systems for buildings.
Know the factors to consider when working to maximize integration of electrical and HVAC system design to achieve economic and operational benefits.
The June 21, 2018, “Electrical: Distribution equipment” webcast presenters addressed questions not covered during the live event.
There has been a move away from traditional lighting controls approaches, which have only incrementally improved over decades, and toward an entirely new way of thinking about, designing, and implementing lighting controls—wirelessly, with internet connectivity, and in an individually addressable capacity all at once.
It is useful for both electrical and nonelectrical engineers to understand basic features when selecting, specifying, and applying electrical distribution systems.
Additional information from the July 28 Lighting: LED specifications webcast includes details about color shift, American Medical Association recommendations, and lighting controls. Presenters Haley Darst and Richard Vedvik tackle multiple questions.
Engineers should know the NIST and ASHRAE standards for the Smart Grid, and be aware of the availability of Smart Grid-ready products for commercial buildings.
