Power Continuity designs builds and installs fully automatic critical power protection systems. When Power Continuity required a maximum efficiency Static Switch with a reliable track record for their major global automotive clients, they looked long and hard at the static transfer switch (STS) options available in 2018 from a number of manufacturers. Following extensive tests, Power Continuity chose Socomec STATYS transfer systems.
John East, Project Director of Power Continuity, said that Socomec STATYS transfer systems were chosen for their reliability and rapid transfer times. The technology allows for plant segmentation and intelligent fault maintenance, therefore increasing the global uptime of the supplied system.
“Offline is simply not an option for our customers,” commented John East. “The consequences of downtime are significant and can impact public safety, as well as business continuity,” he commented.
The Static Transfer Switches (STS) transfer critical loads from one source to another, enhancing power availability while simplifying the electrical architecture. Supplied by two independent sources, STATYS provides redundant power to mission critical loads, increasing the power supply availability by selecting the best quality power supply and preventing fault propagation.
These intelligent switching units transfer the load to an alternative source when the primary source is out of tolerance – ensuring high availability of the power supply for particularly sensitive or critical installations.
The project with this leading power continuity client included the installation of 9 x 200A STATYS cabinet version units for global critical IT loads and 1 x 800A STATYS cabinet version for mechanical loads. In the event of a power failure, Socomec’s STS transfers the load from “preferred” to “alternative” source in typically 3-5mS. Using Silicon Controlled Rectifiers (SCRs) – fast acting switching devices – the switching is carried out under processor control. With inbuilt component redundancy (power supplies, micro controllers and SCR driver boards) reliable operation is guaranteed.
Available with either 3 or 4 pole switching to match the neutral and earth of the installation, the ATSM transfer function manages switching to limit inrush current, therefore avoiding the risk of spurious breaks when supplying downstream transformers.
“Socomec has developed a range of low voltage switching components and protection systems to guarantee power availability in critical applications,” commented Colin Dean, Managing Director of Socomec. “We invest heavily in pioneering research and product design in order to deliver reliable, cost-effective power solutions which can be scaled to meet rapidly changing capacity demands. By working in partnership with design, build and installation experts, Power Continuity, we have delivered the optimum solution for this high profile manufacturing brand in terms of maintaining critical loads while guaranteeing business continuity.”
