The SEL-2730M Managed 24-Port Ethernet Switch and the SEL-2740S Software-Defined Network Switch have received KEMA Type Test Certificates after evaluation by KEMA Laboratories. The certificates validate conformance to IEC 61850-3 environmental standards and IEC 61850-90-4 Ethernet networking performance standards.
Both SEL switches provide network solutions for electric utility substations. The SEL-2730M offers a traditional networking solution, and the SEL-2740S uses software-defined networking (SDN) to improve Ethernet performance in mission-critical applications.
The SEL-2740S is the first SDN switch to be certified by KEMA to IEC 61850 standards. This certification confirms SDN’s infrastructure interoperability and its readiness for use in IEC 61850 solutions.
During conformance testing, the SEL-2740S consistently achieved microsecond-level network healing after triggered network failures. In many of these triggered failures, the SEL-2740S did not lose a single packet of information.
KEMA Laboratories are operated by the quality assurance company DNV GL, which provides independent testing and verification services to the global energy industry. DNV GL has published webpages for the SEL-2730M and the SEL-2740S in recognition of the successful type testing and certifications.
