❯❯ 10 cover story Those who seek out standby and prime power solutions rely on partners who are up to speed. Who stand ready with ideas. Who are, in a word, “on.” Kohler® is that partner, on because the people behind the name are on. Always. borrow heavily from the technical foundation provided by the U.S. Army Corps of Engineers (USACE) Power Security Enhancement Program whose technical manuals, used in the design and operation of Command, Control, Communications, Computer, Intelligence, Surveillance, and Reconnaissance facilities have been released for civilian distribution.1 Because the geometry of regional critical infrastructure typically is widely scattered, keep in mind that the risk assessment methods described here can be scaled outward to encompass an entire city, county, or state. The emergency operations plan required in 708.64 should reﬂect a comprehensive understanding of critical operations as a system-wide entity that may encompass several locations networked together as a single operation. STEP 1: DETERMINE LOCATION(S) A template for a regional risk assessment was introduced before the 2008 NEC went to print, before it had been established that the technical panel assigned to the task was dealing with a Chapter 7 special system rather than a Chapter 5 special occupancy. The article included a qualitative discussion of how jurisdictions might rank regional risks. Simply put, DCOAs had to be scaled according to the relative likelihood of natural or human-made disasters.2 In a follow-up article, a nominal prioritization procedure that resembled a mode criticality “multi-voting” technique promoted by the American Society for Quality was used to produce a disciplined regional risk assessment. An example ranking the likelihood of earthquakes, convective weather, and pipeline accidents was tabulated for a southeastern Michigan county.3 In identifying candidate locations that can meet 708.5 requirements for physical security, it is likely that adopting jurisdictions will have a choice of existing emergency response/disaster management centers. After all, there has been a great build-out of emerwww.purepowermagazine.com gency management facilities—even before Article 708 came along—and we have to assume that they are able to communicate with one another. It’s important to keep communication channels open, so the writers of the 2008 version of Article 708 appended references to the signaling between these agencies in Annex G: Supervisory Control and Data Acquisition. The same topic is covered in substantial detail elsewhere.4 Ideally, COPS should not contain a single point of failure that would allow both the normal electrical service and the emergency backup power to be affected by a single incident. This is more difﬁcult to achieve than it ﬁrst appears with only one transfer switch. Figure 1 shows a very common oneline diagram for a small facility supplying telecommunication, security, and computer equipment in which we have assumed that all the architectural and site security risks have been mitigated. The normal design for uninterruptibe power supply (UPS) batteries is 10 to 15 min, providing power continuously to the UPS output while Utility Generator And whether we’re providing a turnkey system to protect your most critical applications or thinking through an eminently effective solution to a unique challenge, you’ll know the power will be on, guaranteed.
