Grid Feeding Monitoring Relays
Reliable grid feeding monitoring
The multifunctional grid feeding monitoring relays of the CM-UFD range are designed to monitor several grid parameters when feeding energy into the public grid. The intention is to trip a 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. Different monitoring functions such as 10-minutes average value, real time over- and undervoltage as well as over- and under-frequency are configurable via the front face display.
Main Benefits
Safe and reliable monitoring of all important grid parameters
High on grid times increase your revenues
Latest approvals supports your installation complies to your local grid feeding standard
Main Features
Monitoring of voltage and frequency in single- and three-phase mains (2-wire, 3-wire or 4-wire AC systems)
10-minutes average value monitoring
ROCOF (rate of change of frequency) monitoring configurable
Vector shift detection configurable
Error memory for up to 99 entries (incl. cause of error, measured value, relative timestamp)
Password protection
