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. 

The evolution of data center technology is outpacing changes in nearly every kind of commercial building, making the data center installation and service market lucrative. However, it comes with plenty of challenges.

Last month, we looked at how dark fiber is tested to determine its capability of supporting newer, faster transmission networks. Once dark fiber has been tested and its usability confirmed, communications systems can be connected.


Some cabling industry stakeholders predict the imminent death of copper cabling, while others disagree. However, most agree that fiber optical networks are taking a large bite out of the new network market.


This month, we honor perhaps the most notable person in the history of the power quality (PQ) industry, often called the father of PQ monitoring: Abraham I. Dranetz. Some of us knew him as Abe, and others knew him as Mr. Dranetz.
