Overall Reliability and with Zero Packet Loss

(Tested by KEMA)

The EMI stress in high-voltage substations may cause errors or equipment damage in electronic communications. This is not a problem because Moxa's entire line of PowerTrans Ethernet switches are IEC 61850-3 and IEEE1613 certified; the tests were conducted by KEMA, a well respected testing laboratory in the energy and utility markets. Moxa's PowerTrans series switches are designed to withstand all of the EMI type tests required by IEC 61850-3 without experiencing any communications loss. Other tests, including GOOSE messaging, EMC tests, extreme temperature tests, and mechanical tests for vibration and shock resistance were also conducted to verify the overall durability of the PowerTrans series.

Maximum Availability with Ethernet Redundancy and Dual Isolated Power Inputs

Moxa's PowerTrans switches feature the highest level of reliability thanks to Gigabit Turbo Ring™ and RSTP/STP (IEEE802.1W/D) technology to offer fast network fault recovery (< 20 ms). Maximum uptime is ensured with the switches integrated dual isolated redundant power supplies for 24/48 VDC, or 110/220 VDC/VAC to offer you maximum recoverability.

Full Gigabit Performance to Optimizes Network Backbone

Moxa's PT-G7509 full Gigabit Ethernet switch is well suited for high bandwidth applications found in substation automation. The PT-G7509 offers maximum performance and real-time video, voice, and data transmission via a highly flexible deployment of Gigabit ports.

Layer 3 Routing for Large-scale Substation Networks

Layer 3 routing improves large-scale substation network performance. Moxa's PT-7828 layer 3 Ethernet switches are capable of dividing a large network into hierarchical subnets to allow smooth traffic flow and network efficiency.
