The PowerTrans PT-7728-PTP switches are designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613). The PT-7728-PTP’s redundant ring, and dual isolated redundant power supplies increase the reliability of your communications and save on cabling/wiring costs.
Moxa’s PT-7728-PTP IEC 61850-3 Fast Ethernet switches support the latest version of IEEE 1588 technology (IEEE 1588v2 PTP) to fulfill precision time synchronization requirements for 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 by letting you install up to 14 IEEE 1588 Fast Ethernet ports or up to 24 non-IEEE 1588 Ethernet ports and 4 Gigabit ports. 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.

IEC 61850 Substation Solutions

IEC 61850 Substation Solutions BrochureMaximizing a power substation’s availability and safety is the ultimate goal for both transmission grid operators and SAS (Substation Automation System) integrators. A properly optimized SAS ensures safe and continuous operation of substations. This brochure examines some key application scenarios that involve availability and safety, and considers the practical concerns electricity suppliers must account for when planning substation upgrades. In each case the focus is on how Moxa’s communication and computing solutions best minimize error probability, detect errors faster, and speed up fault corrections within the context of IEC 61850.......more
