Substation Automation

Ethernet networks in substation automation applications

A substation offers perhaps the most demanding environment for electronic products imaginable. The high levels of EMC (Electromagnetic Interference) in combination with the critical data in the network makes data communications in substation automation applications particularly difficult to achieve. Not a single data packet may be lost in the data communication between the various IEDs (Intelligent Electronic Device) and the control system. This places extreme demands on the network switches.

Ethernet Network for Substation Automation

Westermo solution

The RedFox 5700 series has been tested and certified by KEMA Labs in the Netherlands, the world's leading test laboratory for high-power components. Most switch manufacturers on the market choose to certify only certain ports because it is extremely difficult to achieve complete compliance. RedFox from Westermo is one of the few Ethernet switches on the market that has received Kema Labs Gold Certification for IEC 61850-3, Class 2, on all ports.

Even though the environment in substations offers major challenges for Ethernet technology, the industry has nevertheless adopted it as an industry standard. The reasons for this include the simplicity of installing and configuring Ethernet networks and the widespread use of Ethernet in other industries and infrastructure systems. 

Westermo offers additional system simplicity through its 'Made Easy' concept, which makes network configuration and management even easier. The network products are powered by WeOS, the most tested and reliable operating system available. WeOS in combination with the KEMA-certified hardware creates an extremely robust, reliable, and easy-to-use network solution for substation automation.
