Standardization, in link with mandate M/490, of measuring relays and protection equipment used in the various fields of electrical engineering covered by CENELEC, taking into account combinations of devices to form schemes for power system protection including the control, monitoring and process interface equipment used with those systems. Moreover, works on standards for electrical connection to ensure energy availability and security, in presence of a high ratio of Distributed Energy Resources (DER) and allowing connected generators to participate to new ways of operating grid (e.g. associated in VPPs or micro grids)". Excluded are the following: All devices covered by standards prepared by other CENELEC technical committees, for example instrument transformers.
