20 Channel Branch Circuit Monitoring Device with RCM Residual Current Monitoring (RCM) Powerful RCM residual current monitoring already detects leakage currents in their initial stages before they cause system failures or even fires. It is already integrated in certain UMG measuring devices. The measuring current transformer that is required can be installed manually at a later date if required. Continuous RCM monitoring increases the system safety and availability significantly. In specific applications such as the data centre, residual current monitoring is essential due to the high availability requirements. 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 analysers. 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. Alarm management The alarm management feature in GridVis® monitors all measurement parameters captured by the UMG measuring devices. It comprises escalation management, a logbook function and user management for individual notifications by e-mail, dialogue box on the monitor, etc.
