The development of a Storage Area Network (SAN) system involves long-term testing, requiring uninterrupted power for periods of up to several months. Custom solutions must be validated on a tight schedule to meet customer commitments. But such testing must be restarted if the equipment experiences a power interruption of just a few cycles . . . wasting valuable time and money. Continue reading
After a power outage resulted in “lights out” with chips on the table, the management of a casino in Arizona realized that power protection involved more than just keeping their gaming machines running. They wanted protection above and beyond that provided by their backup generator and the UPSs embedded in the gaming machines. They wanted a system that would protect their entire facility, give them “blink-proof” transitions between utility and generator power, provide redundancy to their machines’ UPSs, and not take up any valuable indoor real estate . . . a very tall order! An S&C PureWave UPS System met their requirements and more. A 480-volt, 1250-kVA/1000-kW system was installed and commissioned in August 2005. Continue reading
Wanda K. Reder, Vice President of S&C’s Power Systems Services Division, has been appointed President Elect of the IEEE Power Engineering Society. This appointment begins her six-year commitment to providing strong leadership for the IEEE Power Engineering Society and helping shape the future of the electric utility industry. Wanda will be President Elect in 2006 and 2007, President in 2008 and 2009, and Past President in 2010 and 2011. During her tenure, she plans to focus on addressing the industry-wide concern for attracting new technical talent, to help ensure the future of the industry.
Wanda’s career experience working with utilities and utility service providers has uniquely qualified her for this position . . . and helped her develop strong leadership skills. “Being President Elect of the IEEE Power Engineering Society is a great honor,” says Ms. Reder. “I would like to thank everyone who supported my nomination and encouraged me during the campaign. I look forward to serving the IEEE Power Engineering Society and the greater electrical utility industry over the next few years.”
One of the largest utilities in Brazil has 80 Mark V Circuit-Switchers installed on their transmission system — custom-engineered to mount on 50-foot-high tower structures. A recent expansion of their system called for the installation of three new Mark V Circuit-Switchers and retrofitting of two existing Mark III Circuit-Switchers. The five Circuit-Switchers were to be furnished with automation controls that would allow them to be operated by the utility’s SCADA system. The challenge: finding a cost-effective way to provide control power to the associated Type CS-1A Switch Operators. Continue reading
Battery reliability is the number one concern of users of UPS systems. Conventional UPS systems subject the batteries to continuous ripple current from front end rectifiers, and limit battery management strategies in double-conversion systems. S&C Electric Company has pioneered a unique UPS design that allows for a more comprehensive battery management program, providing an enhanced level of reliability and system availability.
This paper discusses S&C’s battery management program and presents its field proven results. Click here for the full paper.
An expansion project at a federal prison facility in Oklahoma called for the construction of several new buildings and upgrading of the existing medium-voltage distribution system. The existing system included nine units of S&C Remote Supervisory Pad-Mounted Gear . . . three additional units were to be installed as part of the upgrade.
The existing gear was equipped with customer-specified remote terminal units that never fulfilled performance expectations. These RTUs were to have permitted remote operation of the gear and provide real-time data from a master station but did not do so. More reliable supervisory control was sought during the expansion project, to ensure that the distribution system could be transferred to a second utility source in the event the primary source was lost.
