MONITORING RELAY CM-UFD.M31 GRID FEEDING

The CM-UFD product line's multifunctional network monitoring relays monitor multiple electrical grid parameters when energy is fed into the public electricity grid. The purpose is to disconnect the supply connected between distributed energy generation (e.g., wind, solar) and the public electricity grid, so that distributed energy generation can be isolated if problems arise in the grid (e.g., unstable grid), faults, or during maintenance. Various monitoring functions, such as 10-minute average, real-time over- and under-voltage, and over- and under-frequency, can be set using the front panel buttons.

Benefits

• Safe and reliable monitoring of all important electrical grid parameters
• Improved grid usability enhances its profitability
• The latest approvals ensure that the installation complies with local grid standards

Features

• Monitoring of voltage and frequency in single- and three-phase electrical grids (2-, 3-, or 4-wire AC systems)
• 10-minute average monitoring
• ROCOF (rate of change of frequency) monitoring configurable
• Vector shift detection configurable
• Error memory for up to 99 entries (including error cause, measured value, timestamp)
• Password protection
