In this new context, the protection systems of national transmission networks must guarantee more than in the past, specifically:AccuracySelectivitySpeed of interventionProtection relay technology for power grids evolves through new measurement algorithms due to the increasing number of functions in a single unit (protection, monitoring, regulation, control, communication and recording). How Thytronic XMORE protects power networksThe XMORE platform is the latest Thytronic product line to protect power generation, transmission and distribution. It covers all energy market solutions: utility, renewable generation, oil and gas, transportation and large energy-consuming industry. Thanks to the modularity, any specific application is covered by XMORE IEDs: feeder, power and distribution transformer, motor and generator, and capacitor bank protection. According to the South African grid code, the Loss of Main is performed mainly by two protection functions: Rate of change of frequency 81R and Vector shift (also called vector jump).
