From the introduction of the P4A, the first digital relay in 1982, to the first protection relay that incorporated Ethernet communications, to the first applications that use digital communications, enabling IEC 61850 Process Bus, GE’s Multilin products and services continues to lead the way, making new protection, control and automation applications possible.

Multilin products offer complete support for IEC 61850 communications directly embedded in to the protection and control relays, meters, substation gateways and HMI. With the widest range of IEC 61850 enabled devices, Multilin simplifies the protection, automation, metering, monitoring, and control of individual assets across the entire power system. The UR 7.3 release adds IEC 61850 Edition 2 and a Single settings file in line with the IEC61850 Substation Configuration Language (SCL) that enables third party IEC61850 configuration tools to directly configure all UR settings, which exceeds expectations from the IEC61850 standard. This enables resources and platform managing optimization and reduces cost of ownership.
