The State Grid Corporation of China (SGCC), the largest electric power transmission and distribution company in China, has selected Moxa's IEC 61850-3 Ethernet switches for use in substation automation and Smart Grid applications. Hundreds of Moxa's PowerTrans series of IEC 61850-3 compliant industrial Ethernet switches will be installed in 500/220 kV high voltage substations, where they will create highly reliable communications networks in harsh electric utility substation environments.

The PowerTrans series emerged as the clear leader after a rigorous and extensive selection process that evaluated several potential global suppliers of substation-hardened industrial networking equipment. Selection criteria included exacting requirements such as EMI shielding that can deliver error-free performance in a variety of destructive EMI stress scenarios.

"This project reaffirms Moxa's commitment and expertise in delivering solutions that will accelerate the "Smart Grid" revolution. Digital technology allows suppliers to deliver electricity to consumers in a more intelligent and efficient way, and are a key component of strategies to minimize resource consumption. Moxa's wide selection of rugged IEC 61850-3 products are certified ready for use in the demanding environments of power applications to create the Smart Grids of the future." explained Leo Tsao, senior director of Moxa Power and Transportation division.

Moxa's PowerTrans series of products are specifically designed to operate reliably in harsh electric utility substation environments. The entire product line has passed IEC 61850-3 and IEEE1613 certification testing conducted by KEMA, and features strong EMI immunity, -40 to 85°C operating temperature range, and redundancy functions for complex, high voltage substations.
