Description
THE LINE supply monitoring relay CM-UFD.M31 monitors voltage and frequency in single and three-phase networks. In conjunction with inverters with integrated island grid detection, it meets the requirements for NA protection according to VDE-AR-N 4105:2018-11 (generating systems on the low-voltage grid) or VDE-AR-N 4110:2018-11 ((generation systems on the medium-voltage grid). For use in old systems, the setting values can also be selected according to VDE-AR-N 4105:2011, or BDEW (infeed on medium-voltage network). The last 99 shutdown causes and their respective time are stored in an alarm memory. The connected coupling switches, vector jump detection and ROCOF frequency gradient monitoring are also monitored.
