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. 

In 2009, Home furnishings retailer Havertys launched a sustainability program using a data-driven energy-management system to pinpoint inefficiency. After implementing a discrete energy-monitoring system, it was able to reduce overall consumption by 20 percent.

Electrical contractors work hard to learn their business and understand how to complete a project professionally and make a profit. The profit part ensures ECs can stay in business. The professional part is mandatory if ECs want to stay in business and grow.

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
