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. 

Last month, I covered the challenges to traditional structured cabling from multimode optical fiber and wireless. Multimode fiber became the favorite cabling for the backbone but never made it to the desktop because every connected device already had a free Cat 5 port.

In this third part of my series on the most common power quality phenomena, I group several IEEE 1159 categories together under the general description of “distortion.” Though one might argue that all power quality phenomena result in distortions of the voltage sine wave, these are the more steady-s

Positioning


About three years ago, security service providers started offering smart security solutions complete with professionally monitored home security services that were enhanced with home automation and energy management capabilities.

There is no shortage of organizations predicting what the construction market will look like in 2014. We have all experienced how poorly predictions may work out in some areas (e.g., the weather).

Is Copper Cheaper than Fiber?
by Staff |

Fiber optics is always expected to cost much more than copper cabling. Whatever you look at—cable, terminations, or networking electronics—fiber costs more. So isn’t it obvious that fiber networks are more expensive than copper? Maybe not! There is more to consider before deciding this.
