Consulting-Specifying Engineer‘s top 5 articles online over the past week covered electrical power quality, lighting controls, evaporative cooling options, office buildings and single-pair Ethernet. Were you out last week? Catch up with a link to each article below.
1. Electrical power quality and system harmonics: Practical options exist – Harmonic distortion resolution of variable frequency drive motor applications will provide the most beneficial actions for IEEE 519 compliance.
2. How to use sequence of operations for lighting controls – Sequence operations provides a clear, concise and client-friendly method of communicating lighting design intent.
3. How to know which evaporative cooling option is right – When considering evaporative cooling, understand the general applications and high-level engineering considerations.
4. Office building electrical, power system design has changed – COVID, employee well-being and indoor air quality issues have all changed the way office building electrical and power systems are considered.
5. How single-pair Ethernet can simplify your data network – Single-pair Ethernet (SPE) is exactly what it sounds like, an Ethernet cable that has one twisted pair of copper conductors rather than the usual four.
