Introduction
The PowerTrans PT-7528 series is designed for power substation automation applications that operate in extremely harsh environments. The PT-7528 series supports Moxa’s new Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed. The PT-7528 series also features critical packet prioritization (GOOSE, SMVs, and PTP), a built-in MMS server, and a configuration wizard designed specifically for substation automation. With Gigabit Ethernet, redundant ring, and 110/220 VDC/VAC isolated redundant power supplies, the PT-7528 series further increases the reliability of your communications and saves cabling/wiring costs. The wide range of PT-7528 models available support multiple types of port configuration, with up to 28 copper or fiber ports and 4 gigabit ports for uplink. Taken together, these features allow greater flexibility, making the PT-7528 suitable for a variety of industrial applications.

IEC 61850 Substation Solutions
Maximizing 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

Making Smart Substations Even Smarter: Enhancing Substation Reliability, Availability, and Maintainability
This paper sketches out a few of the more important concerns that electricity suppliers should account for when planning substation upgrades. The focus is on how best to increase the reliability, availability, and maintainability of power substation automation networks within the context of the IEC 61850 vision, to give electricity suppliers a clear idea of the design procedures, device tolerances, and hardware and software features they should expect from the engineers and manufacturers who design and build their networking and computing devices.......more

Using MMS and SNMP to Integrate IT Management for Substation Automation
The devices that electrical substation automation systems are built from depend on highly precise, time-critical communications. Substation thus often use highly specialized monitoring systems to tackle this problem, but can approach it using different technologies. The most up-to-date, “smart” substations use the Manufacturing Messaging Specification (MMS) for communications among IEC 61850 intelligent electronic devices (IEDs), allowing SCADA to monitor and control IED states as well as process switchgear and transformer data directly. However, IT networking devices have been increasingly applied in IEC 61850 systems, and this equipment communicates using SNMP. Consequently, in the modern substation automation industry it’s clear that, for the time being, SNMP and MMS will continue to exist side-by-side. For designers and integrators of electrical substation equipment, bringing both MMS and SNMP support to IT equipment is an ideal, one-size fits-all alternative that allows for the greatest flexibility and adaptability around........more
