Multifunction power analyser with RCM

The multi-purpose unit for integration into control panels. Continuous monitoring of the power quality, analysis of electrical interference in the event of network problems.

Main features

  • Power quality

    Reliable operation of modern plants and systems always demands a high degree of supply reliability and good power quality. UMG measuring devices reliably record, analyse and document all interferences such as harmonics, unbalance, transients, voltage dips, voltage swells, flickers, phase shifts and reactive power.

  • 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.

  • Ethernet-Modbus-Gateway

    The Ethernet Modbus gateway can be used to easily include the Modbus RTU devices that are connected to the master device as slaves in an Ethernet architecture. This is also possible via a Modbus RTU interface for devices with identical file formats and matching function codes.

  • Reporting

    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.

  • 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.

    In addition to monitoring effective values, short term interruptions and transients, as well as communication with the measuring devices can also be monitored.

APPs including

Measurement monitor

Configurable display of current and historical measured values with automatic scaling. Graphical representation on the device's own homepage without additional software installation.

IEC 61000-2-4 Watchdog PRO light

Permanent monitoring of the power quality based on EC 61000-2-4 in customers' energy supply networks.

Areas of application

  • Continuous monitoring of the power quality
  • Energy management systems (ISO 50001)
  • Master device with Ethernet gateway for subordinate measurement points
  • Visualisation of the energy supply in the LVDB
  • Analysis of electrical disturbances in the event of power quality problems
  • Cost centre analysis
  • Remote monitoring in the property operation
  • Use in test fields (e.g. in universities)

The new generation – the UMG PRO series

The new PRO series combines the latest technology with excellent functions and attractive design. The increased variety of functions and comprehensive illustration options enable measurement data and measurement results to be analysed and interpreted more easily. Data can be processed, visualised and analysed with the help of the pre-installed Janitza APPs. APPs are a function extension of the device homepage. The traffic-light principle makes complex power quality analyses, for example, understandable for everyone.
