"It's more reliable and secure." In fact, it's protect- equipment vendors. ed with 128-bit AES encryption, the same encryption used by National Aeronautics System performance also would need power-quality analytics to evaluate and diag- and Space Administration (NASA).

ISSUES A THING OF THE PAST ment is part of the team's effort to support hospital operation. Transitioning to fuller, faster, and more accurate and capable critical-power manageThat was about a year ago. Today, Liedman and Tester report that problems with testing "It's all about competing pressures on the provision of healthcare," Liedman said. and managing critical power day to day are a thing of the past. The new system the "It's a very competitive healthcare environment here." Although patients don't see the hospital installed, the ASCO 5750 PowerQuest Critical Power Management System, critical power infrastructure, it has to ensure hospital operations don't miss a beat meets the list of must haves. should the utility source go down. No more nightmares, just sweet dreams. CBP What they like best about it is, as Tester said, "It works!" Liedman said, "It responds instantaneously. The big win for us is automated reporting and trending, which was all new to us. Before, everything was handwritten. Now, we generate reports that are tailored to meet the requirements of healthcare facilities so they're perfect for our monthly run report. That hits the mark for us." Trending shows them power demand history so they know where they have adequate capacity and, more importantly, where they don't. They overlay that with future construction plans, which help them project critical-power-system scaling to keep it in lock step with hospital growth and kilowatt demand. While they still manually enter some data, their conﬁdence in digitally managing critical power continues to build and, at some point, they see themselves relying exclusively on auto-generated data. They also can produce reports on bypass status, critical power settings, diagnostics, alarming, and historical logs. Want more information?

MANAGING THE POWER INFRASTRUCTURE They manage the hospital campus' entire power-distribution system, beginning at the true dual 13.8-kV back-to-back utility source feeds. The on-site power feed design is a main-tie-main conﬁguration with six pairs of downstream, end-to-end substations. Transformers step down power to 480 V. The central power plant comprises three 480-V, 1,000-kW gen-sets. They provide N+1 pow- Varco Pruden's Innovative Daylighting Solution PRISMAX SL™ PrisMAX SL provides more light for longer periods of the day, enhancing a wide variety of indoor activities for customers, employees and visitors in your facility. These durable skylights use prismatic lens technology to deliver optimal daylight performance. PrisMAX SL was developed in conjunction with Sunoptics™ and when used as part of a sensored-controlled lighting package reduces the need for electrical lighting. er redundancy as the total load on the gen-sets is about 1,500 kW. "Reliability is a big concern of ours, of course," said Tester, "so the redundancy helps ensure power will be there when it's needed." Ensuring reliability also is why they are about to replace the system's 25-yr.-old generator paralleling control switchgear that synchronizes and manages the gen-sets. Thirty-four automatic-transfer switches help power loads and range from 150 to 1,200 A, with most rated between 400 and 800 A. They are a variety of bypass-isolation, Designed to work on Varco Pruden's SSR™ or HWR™ roof systems, PrisMAX SL's unique "self-curbing" structure uses a patented water-diverter and seam-mounted aluminum framing to create a long term, weathertight seal for years of maintenance-free performance. closed-transition transfer, open-transition transfer, and delayed-transition transfer modes of operation to satisfy the demands of varying types of loads-from data center computer equipment to motors. Liedman said, "With the dual feeds, power generation, and transfer capacity and With Varco Pruden's PrisMAX SL, you can expect: new critical-power management capabilities, we have a power infrastructure that's hard Reduced lighting costs to beat." Diffused lighting without hot spots Ideal for existing buildings or new construction They conduct tests with real loads, which include life safety and critical branches, Environmentally friendly, low maintenance performance clinical equipment such as MRIs, some business-occupancy spaces, and a data center Build Smart, with a 125-kVA uninterruptible power system used as a ride through.

"We notify With Varco Pruden Buildings them as a courtesy, but they almost never realize there's a difference in the power source." DYNAMIC VISUALIZATION Monitoring critical power 24/7 is a given, of course, so overnight the boiler operator relies on the power-management system's dynamic visualization to present information in an easily understandable format.
