(PRWeb UK) April 7, 2011
Gloucestershire based energy expert SIEL, in conjunction with Prism Power, has recently completed the first installation phase of 56 bespoke ‘EXCHANGE’ 4 pole Static Transfer Switches (STS) at NYSE Euronext’s new ‘ State of the Art’ UK data centre.
Eighteen STS systems, each rated at 1,600Amps complete the first phase. The whole package has been constructed to meet stringent customer requirements and specifications, including ASTA 80kA fault rating certification and form 4.7 segregation/separation. These are one of the first STS systems to meet such stringent specifications as a composite system.
The custom IP31 STS enclosure is designed to accommodate easy termination of multiple large single core feeder cables and to form a compatible part of a matching 96 way intelligent PDU suite supplied by Prism Power. The STS input section includes dual mains inputs with manual wrap around bypass Mccb’s in the lower section operationally interlocked by ‘castell’ keys . Connection of the STS to the PDU suite is made via a solid internal bus bar connection. The STS units having been designed to provide future flexibility by facilitating either ‘right or left’ handed connection to the PDU’s via a separate transition section. The full functionality and status of the STS and PDU intelligent output ways are fully monitored by the customers SCADA system using integrated Modbus interfaces.
Siel’s EXCHANGE STS is provided in 4 pole configuration and achieves an automatic transfer from the preferred supply source to the alternate supply typically within 4msec’s (1/4 cycle). Both input supplies being derived from the output of rotary UPS Systems. Other features include delayed ‘retransfer’ back to the preferred supply source in the event of a transfer being initiated.
As well as the bespoke systems, 4 off 160A 4 pole EXCHANGE systems that meet NYSE’s standard specification have been supplied to enhance security of supplies to other critical equipment. Full ModBus remote monitoring of each system is provided via individual STS synoptic graphics displayed on SCADA screens located within the overall facilities control/command centre.
