Power quality

  • Harmonics analysis up to 63rd harmonic
  • Acquisition of short-term interruptions
  • Acquisition of transients
  • Display of waveforms (current and voltage)
  • Unbalance
  • Vector diagram

RCM (Residual Current Monitoring)

  • Continuous monitoring of residual currents (Residual Current Monitor, RCM)
  • Alarming in case a preset threshold fault current reached
  • Near-realtime reactions for triggering countermeasures
  • Permanent RCM measurement for systems in permanent operation without the opportunity to switch off
  • Ideal for the central earthing point in TN-S systems

Modern communications architecture via Ethernet

  • Ethernet interface and web server
  • Faster, better cost-optimised and more reliable communication system
  • High flexibility due to the use of open standards
  • Integration in PLC systems and BMS through additional interfaces
  • BACnet optionally available
  • Up to 4 ports simultaneous
  • Versatile IP protocols

Modbus Gateway function

  • Economical connection of devices without Ethernet interface
  • Integration of devices with Modbus-RTU interface possible
  • Data can be scaled and described
  • Minimised number of IP addresses required

Graphical programming

  • Comprehensive programming options (PLC functionality)
  • Jasic® source code programming
  • Sustainable functional expansions far beyond pure measurement
  • Complete APPs from the Janitza library

Powerful alarm management

  • Can be programmed via the graphic programming or Jasic® source code
  • All measured values can be used
  • Can be arbitrarily, mathematically processed
  • Individual forwarding via email sending, switching of digital outputs, writing to Modbus addresses etc.
  • Watchdog APPs
  • Further alarm management functions via GridVis®-Service alarm management

Device homepage

Assessment available at all times

Each measurement device has an integrated web server, which has a separate homepage. The measurement device can be operated in the same way via its homepage as with the device display.

Furthermore, extensive current and historic measurement data, including the power quality analysis, can also be called up. An advantage of the device homepage is the constant availability of the measurement data – without prior software installation.

The user can immediately obtain an overview of all energy data. The device homepage can be displayed on any end device and will be adapted to suit the device functions (Responsive Design).

Simple operation is possible thanks to the uniform design of the GridVis® visualisation software and the device homepage.

Your benefits:

  • Access to powerful device homepage via web browser
  • Constant availability of the measurement data
  • No software installation necessary
  • Online data, historical data etc. can be called up directly via the device homepage
  • Function expansion possible through APPs
  • Remote operation of the device display via the homepage
  • Integrated PQ watchdog
  • Hyperlinks deliver more detailed information
  • Integrated measured value monitor
  • Overview of events and transients in the network
  • Convenient selection of the calculation mode for displaying the measurement data per standard IEC 61000-2-4 or EN 50160 (Applies to UMG 605-PRO and UMG 512-PRO)
