Moxa, a leading provider of industrial networking solutions, announced that its full line of PT series Ethernet switches has passed KEMA tests based on IEC 61850-3 and IEEE 1613 standards, which specify environmental and EMI immunity requirements for network equipment in substations. Founded in 1927, KEMA is a global provider of business and technical consulting, operational support, measurement and inspection, testing, and certification for the energy and utility industry. The KEMA tests are designed to simulate actual substation conditions. All tests for the PT series products were conducted in four phases. The first phase is the functional phase, which focuses on IEC 61850-10 conformance, VLAN, and Spanning Tree Protocol (STP) tests. The second phase focuses on EMC, including lightning strikes, thunder, and other electromagnetic interferences. The third phase tests product operability under extreme temperatures ranging from -40 to 85°C. The fourth phase focuses on mechanical aspects and includes vibration and shock resistance testing. The successful KEMA test results attest to the product line's full compliance with IEC 61850-3 and IEEE 1613 standards, as well as ultra reliability for use in challenging substation environments.

These Ethernet switches provide the best features for substation communications by offering strong EMI immunity, -40 to 85°C operating temperature, redundant ring capability, and dual redundant power supplies of 24/48 VDC or 110/220 VDC/VAC for complex and high voltage substations. Maximum flexibility is achieved by a modular rackmount design with high optical fiber and Gigabit port density, making the switches well suited for both retrofitting existing substations as well as establishing networks for new substations. Layer 3 routing is supported for better network performance on large-scale substation LANs.
