Moxa is pleased to announce that the PT-7728-PTP series IEC 61850-3 Ethernet switch proved its capability in substation applications by passing all the compliance and interoperability tests conducted by the State Grid Electric Power Research Institute (SGEPRI) of China. SGEPRI’s testing confirmed that the PT-7728-PTP switch excels in substation applications with its ability to operate under extreme EMI while still fulfilling precision clock synchronization.
SGEPRI is the national standards and testing authority for the electric power industry in China. In its seven labs, the SGEPRI provides inspection, consulting, and training services to devices suppliers and grid operators all along the power chain in China. Passing SGEPRI’s tests establishes Moxa as a leading player in power substation applications.
"The energy demand driven by China’s large population and growing economy has led it to the forefront of smart grid development, so we considered passing the SGEPRI tests a milestone for Moxa,” explained Dennis Lin, product manager at Moxa.
"This testing convincingly demonstrates the product’s reliability in extreme EMI environments and the consistency of Moxa’s compliance with the IEEE 1588v2 standard, which delivers precise timing accuracy in power substations. The PowerTrans PT-7728-PTP Ethernet switch not only provides nanosecond-level time synchronization of SMV streams, but also achieves no packet loss in GOOSE transmissions, making it an ideal product for smart substation systems.”
Moxa's PT-7728-PTP is an IEC 61850-3 and IEEE 1588v2 rackmount Ethernet switch that supports up to 4 Gigabit, 24 fast Ethernet, and 14 IEEE 1588 fast Ethernet ports through port modules. IEEE 1588 v2 support is included to meet the precise time synchronization requirements of protection and control applications. These Ethernet switches guarantee time-stamping accuracy within 1 μs for the IEC 61850 process layer. They can be configured for 1588 v2 Master, Boundary Clock, and Transparent Clock functionality.
The modular design of the PT-7728-PTP also makes network planning easy, and allows greater flexibility in port selection. Along with a choice of either front or rear wiring, these features together make the PT-7728-PTP suitable for a variety of industrial applications.
