Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

We are all aware fiber optics is the backbone of communications networks such as telecom, the internet, local area networks, cable television and more. It’s also the backbone of the electrical grid.

Over the past two years, the technical committee responsible for IEEE 1547, Standard for Interconnecting Distributed Resources with Electric Power Systems, has added a section on power quality (PQ), including the parameters, indexes and limits on those for distributed energy resources (DERs) connect

Mobile applications, an increasingly fluid workforce and improvements in product integration are changing the landscape of mass notification systems (MNSs) and emergency communications. The technology is more responsive and better directed in messaging to the masses.
