A simulative validation of the setting values is necessary in order to verify the setting of these protection devices. Especially in meshed networks and networks with decentralized generation, effects occur, which change the reach of the protection devices. Description Extended Protection Simulation (SZ) Siemens PSS SINCAL Protection Modulesĭistance protection and differential protection devices are primarily used in meshed distribution networks and in transmission networks.
