Ethernet switches for power distribution networks

July 2011 IT in Manufacturing

Moxa has introduced the DIN-rail PT-508/510 series IEC 61850-3 substation switches, the newest addition to its PowerTrans Ethernet switch series. Tailored for the power utility industry, the PT-508/510 series provide the highest level of reliability and availability for substation communications thanks to tough EMI immunity, a -40 to 85°C operating temperature range and redundant features that tackle specific needs and requirements found in power substations. In addition, the switches support Moxa Turbo Chain, a resilient self-healing Ethernet technology, making them well-suited for wide, extended power distribution networks.

Designed for power distribution networks

“A typical power distribution system consists of a complex network with many power utility connections, so system operators are always looking for efficient network connections to address the critical factors found in large power distribution automation applications,” says Leo Tsao, Power and Transportation division, Moxa.

The PT-508/PT-510 series switches feature Moxa’s innovative breakthrough technology, Turbo Chain, allows the creation of multiple redundant networks making it ideal for complex power utility network connections spread over multiple locations with correspondingly complex wiring requirements. Compared with conventional ring topology, Turbo Chain eliminates the need for additional Ethernet ports to form ring coupling paths, as well as the kilometres of cabling that are often required.

IEC 61850-3 certified for power substation environments

As with all of the Moxa PowerTrans products, the PT-508/510 series switches are specifically designed for substation environments. In addition, the switches have passed IEC 61850-3 and IEEE1613 certification and are fully equipped with the features specified by the IEC standard, including horizontal communication with zero GOOSE message loss. The PT-508/510 series Ethernet switches sport an impressive array of features that include an IP40-rated housing, a -40 to 85°C operating temperature range, three or four optical fibre ports and isolated redundant power supplies.
