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. 

Energy costs and potential energy shortages are increasingly driving commercial building and industrial facility owners to find ways to use less energy for the same level of activity.

I suspect that the idea of employing anaerobic adhesives for fiber optics came from someone using Krazy Glue or the two-part adhesive made to fix a car’s rearview mirror after it fell off in the hot summer sun.

In solar installations, ranging from rooftop panels and larger community- and utility-scale arrays, photovoltaics (PVs) are becoming increasingly important to our energy supply.

Damaged dog-fence power source

Lightning is the biggest cause of damage and destruction of electrical and electronic equipment in industrial facilities, commercial buildings and homes, as stated in the 2008 report by the U.S. National Lightning Safety Institute.

Consider it a luxury. As a particular technology matures and becomes widely accepted, a new set of challenges emerge. Such is the case for the smart grid, which is passing the point of being a novelty and entering the realm of accepted practice.

Last month, I discussed one of the most important tools in the fiber tech’s toolbox: the fiber optic power meter. This month, let’s examine the other tool that is equally important: the test source used with the power meter to measure the loss of the cable plant.

Because I Said So

I recently realized that our failure to properly train fire alarm system technicians has created a group of workers who simply do not understand the reasons they do what they do. When a technician asks for the rationale behind a procedure, we often respond, “Because the code requires it.”
