Ensures no interruption of critical loads when transferring between power sources

Hingham, MA - Russelectric, A Siemens Business, a leading manufacturer of automatic transfer switches and power control systems, offers its Paralleling Systems, ideal for ensuring optimal power support for critical loads when transferring between live power sources in data centers, whether they be Utility Paralleling, Prime Power or Open/Closed Transition Emergency Systems. The Utility Paralleling System can also be configured for peak shaving, utility-sponsored load curtailment programs, exporting power to the grid, and for a variety of combined heat and power (CHP) applications.

Protecting Data Centers, and the data they house, is extremely critical. Russelectric paralleling systems incorporate dual, redundant, live synchronized programmable logic controllers (PLCs) for system control. Discrete hardwired components, including switches, meters, and control devices are standard to allow manual control capability, in the unlikely event that both system PLCs fail. In addition, with a Russelectric Utility Paralleling System, users get soft loading transfer and phase lock synchronizing when paralleling with the utility, which reduces transients and controls the loading to the engine generators.

All Russelectric paralleling systems are UL listed. Selector switches are provided for open/closed transition, automatic/manual paralleling of generators and utility sources, and automatic/manual retransfer between both sources of power where applicable.

The Utility Paralleling System offers a choice of either momentary paralleling with the utility or sustained paralleling for soft loading. Also available is paralleling of generator sets with the utility upon return of the utility source after power interruption.

Utility Paralleling System operation begins with testing in closed-transition mode with no interruption of the load. Generators are then paralleled with the utility and the load is transferred to them. Upon completion of testing, the load is retransferred through closed-transition to the utility source without disturbance.
