WRZN - Finding the Path of Least Resistance [PDF - 11 Mb] What makes a good ground? Ideally, it’s a connection to earth that can absorb an unlimited amount of current without changing its potential. This is the type of connection that was created for WRZN-AM in Hernando, Florida. This simple, inexpensive system should keep the station alive and well during any lightning occurrence or power surge.
New Grounding System Ensures Radio Broadcast Stations Remain on the Air [PDF - 4 Mb] Broadcast radio stations can encounter power outages, interrupted programming and costly repairs in the event of a lightning strike. In order to prevent these catastrophes, the MARC Radio Group installed a new code-exceeding grounding system, which has helped ensure uptime for its stations.
Safety Center Tower Grounding [PDF - 393 Kb] Having suffered damage and downtime in the past, Macomb County, Michigan proactively took lightning protection into account when renovating their emergency communications center and satellite facilities. Copper-based lightning, wiring and grounding systems provided the reliability needed.
Fire Station Lightning Protection and Grounding Systems [PDF - 2 Mb] Fire Departments and police facilities are communications centers, sometimes without realizing it. That means grounding, lightning protection, and other power quality considerations are critical to reliability. This case history relates how two Connecticut fire stations implemented cost-effective modifications that improve up-time and can save lives.
Orange County 911: Lives Depend on Power Quality In lightning-prone Florida, a retrofit of several sites operated by Orange County proved the effectiveness and low cost of grounding and bonding properly. This story is applicable to any communications site, including broadcasters as well as public safety.
Involta Data Centers: Copper Wiring Systems Ensure Reliability Involta is a world-class data center operator, with currently six locations. Each serves a variety of tenants, primarily in secondary markets. The centers were built at different times in slightly different electrical architectures, but reliability is the facilities’ first and common requirement. That’s where a copper infrastructure comes in. There are design lessons for every critical application in this story.
100% Copper Ensures Reliability for Nebraska Data Center 100% reliability is the goal at CoSentry, an Omaha-based data center operator with six current locations. From dual electric feeds to dual chillers, continuous availability is the most important need of their customers, and an all-copper electrical system is an integral part of that requirement. Wherever the need is critical, the copper-based wiring methods are the most reliable available.
"Boutique" Data Centers for Small Business Owners? Data centers come in small as well as large sizes, but the need for continuous up-time is still critical. Power Protection Products satisfies the needs of smaller customers with a concept they call LoCoCoLo – a Low Cost Co-Location center. And copper wiring and grounding is a just as much a part of providing reliability here as it is in data centers that are hundreds of times larger.
A Power Quality Primer This paper discusses the basic issues surrounding power quality, from basic definitions to grounding to harmonics, in general terms. Suggestions on wiring techniques and power quality are also included.
Have a Good Power Quality Story to Tell? Engineers, Building Operators, Electrical Contractors, Plant Operations Personnel: CDA is interested in hearing how your company designs its facilities to avoid power quality problems, or took steps to alleviate them.
