IEC 61850 Process Bus - It is Real!

The new international standard for substation communications IEC 61850 allows the development of a new generation of substation protection, automation and control systems that results in significant reduction of the overall cost of such systems, while at the same time improves the functionality of different applications. Non-conventional instrument transformers with digital interface based on IEC 61850-9-2 process bus eliminate some of the issues related to differences in protection and metering requirements. The data can be processed by any device to perform different protection, automation and control functions. More
