Type CM-UFD grid feeding monitoring relay * The CM-UFD.M33 is a multifunctional grid feeding monitoring relay. It trips the section switch which is connected between the distributed generation and the public grid in order to disconnect the distributed generation in case of problems (e.g.unstable grid), faults or maintenance on the grid. The device provides different monitoring functions to detect 10 minutes average overvoltage, real time over- and undervoltage as well as over and under frequency. Additionally, monitoring of vector shift and ROCOF (rate of change of frequency) can be configured in order to trip the generation in case of loss of mains. * Monitoring of voltage and frequency in single- and threephase mains (2-wire, 3-wire or 4-wire AC systems) * Over- and undervoltage, 1O-minutes average value as well as over and underfrequency monitoring * Two-level threshold settings for over-/undervoltage and over-/underfrequency * ROCOF (rate of change of frequency) monitoring and vector shift detection configurable * Interrupted neutral detection * True RMS measuring principle * All threshold values and tripping delays adjustable * Error memory for up to 99 entries (inc!. cause of error, measured value, relative timestamp)
