The UMG 103-CBM is a universal measuring device for top-hat rail mounting in low-voltage distribution systems and is used to measure and check electrical parameters in power distribution systems. It measures harmonics up to the 40th harmonic.
Harmonics
Harmonics occur due to operating equipment with a non-linear characteristic, e.g. transformers used in saturation, energy saving bulbs, frequency converters and power electronics. They cause a load on the mains due to additional currents and can affect or even destroy operating equipment. This mains feedback can be detected and documented using power quality analyzers.
Modbus interface
Many UMG measuring devices have an RS485 interface with a Modbus RTU protocol, which enables extremely cost-efficient networking. It features simple topology configuration and a lack of sensitivity to EMC interference. Communication between the sender and the recipient takes place on a wired basis via a sheathed, twisted pair cable.
GridVis®
GridVis® is a comprehensive and scalable piece of software for setting up an energy monitoring system and monitoring the power quality. It is used to both program and configure many UMG measuring devices, as well as to read, process and analyse the measured data. Typical applications are energy supply, industrial systems, facility management, etc.
Threshold value monitoring
Threshold value monitoring can be assigned to both alarm management and switching operations. Corresponding UMG measuring devices have digital outputs that are suitable as switch outputs. Therefore, certain reactions can be automated if a threshold value is exceeded or not reached.
