Functions and Features

Get a general overview of the most important functions of the UMG 20CM.

  • RCM and energy measurement device in a single unit

    • 20 current measurement channels +/- 0.5 %
    • 4 voltage measurement channels +/- 0.5 %
    • Internal RS485 interface (Modbus as Slave)
    • 20 LEDs – One LED for each current channel (Green = o.k., Yellow = Warning; Red = Nominal current exceed)
    • Measurement range of operation current with burden up to 63 A with closed or split core current transformers (standard measured values: V, A, kW, kVA, kVar, kWh)
    • Fig.: Operating current and RCM fault current monitoring

  • The system for smart people

    • Compact nature of the system
    • Can be retrofitted to existing systems
    • Modbus RTU directly on board
    • State indication per channel (LEDs)
    • Name stored per channel in the measurement device
    • Wide range power adapter (90 – 276 V ... AC / DC)
    • Integration in the GridVis® software
    • Diverse current transformer variants for the individual application
    • Measurement variants:
      • Three-phase and single-phase energy measurement
      • RCM measurement three-phase and single-phase
    • High sampling rate 20,000 Hz
    • Current transformer connection monitoring (i.e. wire break will be detected)
    • Harmonics analysis up to 63rd harmonic via analysis channel
    • Saving of minimum and maximum values with time stamp
    • Standard measured values: V, A, kW, kVA, kVar, kWh (variable list)
    • Scalability of the system

  • Power supply without drop-outs

    • Permanent monitoring and logging of processes in TN-S or TN-C-S systems
    • Simple parameterisation and operation of the RCM measurement
    • Automatic reporting in the event of problems enables a rapid initiation of countermeasures
    • Comprehensive diagnostics increase safety and efficiency of a company
    • Fig.: Message before shut-down - an objective of residual current monitoring

  • Alarms before failures (preventative residual current analysis)

    • Faults arising will be detected in good time
    • Monitoring, evaluation and reporting of creeping increases in residual currents (e.g. triggered by insulation faults and operating currents for system parts or loads being too high)
    • Reduction of downtimes

  • Sensors for energy management

    • Energy data of a large number of loads can be acquired and passed to a database with ease
    • Automatic reading out and saving of the measured values and data saved in the measurement devices as well as the exceedance of parameterised threshold values
    • Channel-specific measured values of the current monitoring devices can be displayed via the GridVis® software
    • The evaluation and saving of data in central databases is implemented via the GridVis® software
    • The greater the scope of information, the more accurate the determination of savings potentials
    • Energy optimisation offers a higher, more economical savings potential (ISO 50001)
    • Fig.: Read-out, analysis and saving of energy data

  • Your benefits - The intelligent system solution

    • Early warning with system failures
    • Avoidance of costly and hazardous system downtimes; the availability of systems is increased
    • Localisation of individual faulty feeders, reduced work when troubleshooting
    • Early detection of an overloading of the N conductor and critical residual currents, resulting in increased fire safety
    • Through parameterisation of the system in new condition and constant monitoring, all changes to the system state after the point of commissioning can be detected
    • Fulfilment of the safety criteria "RCM residual current monitoring" in data centres
    • Convenient monitoring and parameterisation solution with GridVis® software
    • Operating current acquisition of all relevant consumers as a basis for an energy management system (EnMS)
    • Fig.: Constant processes and highly sensitive applications such as data centres, are based on RCM monitoring.
