Reliable grid feeding monitoring according to your local standards
ABB’s CM-UFD range are multi-functional grid feeding monitoring relays, installed between the renewable energy system and the public grid. They detect unusual events in the public power grid and automatically disconnect and reconnect the renewable power plant. Different monitoring functions such as 10-minutes average value, real time over- and undervoltage as well as over- and underfrequency are configurable via the front face display. Versions with a Modbus RTU communication interface are available as well.
