Utility Grade IEC 61850-3 Switch for Digital Substation, Power & Utilities Applications

California, U.S.A., April 2018 – Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions is pleased to share how the Digital Substation, Power and Utilities applications can benefit using Ethernet Direct IEC 61850-3 certified industrial Ethernet switches.

Ethernet Direct pioneers in offering Utility-grade, fully managed Gigabit Ethernet switches specifically designed to operate reliably and safely in harsh environment found in electric utility substations. The HMG-838EPTI6 is an IEC-61850-3 and IEEE 1613 certified industrial Ethernet managed switch that comes with 8 x 10/100/1000Base-T(X) ports and 3 Gigabit/Fast Ethernet SFP ports that provides a high level of immunity to electromagnetic interference and heavy electrical surges to meet the demands of power substation systems. This powerful utility switch uses Made in the USA CPU platform for maximum hardware product reliability and has an operating temperature of -40 to 85°C. It is designed with redundant and isolated power supplies (24/48 VDC and 110/220 VDC/VAC) to protect the substation system.. In addition, the enhanced software features support a variety of Ethernet functions including STP/RSTP/MSTP/ITU-T G.8032 ERPS and multiple Direct-Ring for redundant cabling, IEEE 1588 PTP V2, layer 2 Ethernet IGMP, VLAN, Quality of Service, ACL, Security, IPv6, bandwidth control, port mirroring, cable diagnostic and Energy Efficient Ethernet.

Ethernet Direct smart grid technology products ensure “zero packet loss” and support GOOSE multicasts. The HMG-838EPTI6 is ideal for applications in distribution automation, substation automation, renewable power generation, thermal power generation, power grid interconnection, advance metering infrastructure and more.

According to industry research, the Digital substation market for the utility industry is expected to grow at the highest CAGR between 2017 to 2023. Deploying certified IEC 61850-3 and IEEE 1613 switch ensure safety and reliability. The utility industry is one of the booming application areas pertaining to digital substations owing to the high demand-supply gar in energy in most of the developing and developed countries. This market growth can be attributed to the increase in demand for renewable energy sources, such as wind, solar and hydro in order to meet the growing demand in power generation used for transmitting and distributing power.
