New SVA – Sampled Values Analyser

IEC 61850-9-2 Sampled Values (SV) standardise the transmission of instantaneous power system data over an Ethernet/fibre optic communication channel using a publisher/subscriber mechanism. In a move towards digitalisation of substation architecture, analogue signals transmitted on copper wires are getting replaced with digital signals on fibre optic Ethernet networks. These digital signals are either generated by standalone merging units (SAMU) or compliant IEDs with digital signal processing capabilities. Megger’s SMRT/FREJA test instruments and the SVA software are compliant with IEC 61850 9-2 Light Edition (LE), which is a Utility Communication Architecture (UCA). Rather, it is a Utility Communication Architecture (UCA) profile that has been widely accepted across the world for use in digital substations.
