PureWave UPS Systems Protect Test Labs from Power Outages

Bookmark and Share

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

S&C’s PureWave UPS System Provides Facility-Wide Protection to Casino

Bookmark and Share

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

Power from the Sun: Circuit-Switchers with Solar-Powered Operators

Bookmark and Share

Solar-powered operatorsOne 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

Technical Paper: Battery Management for Ultimate UPS Reliability

Bookmark and Share

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.

Prison Slams the Door on Delinquent RTUs . . . and Chooses Reliable S&C Automatic Switch Controls

Bookmark and Share

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.
