The introduction of the IEC 61850 standard represents a great step forward in substation automation and the process is continuing. One example is the application of the standard’s subsection, IEC 61850-9-2, for the sharing of sampled analog values using Ethernet. By integrating this technology into its substation automation systems, ABB has combined over 10 years of experience in producing non-conventional instrument transformers for current and voltage measurement with the latest communications technologies. It is now possible to connect primary (high-voltage) equipment to ABB’s field-proven substation protection and control devices more effectively, improving the reliability and availability of optimized substations.
