Functions and features

Analysis of fault current events

  • Event list with time stamp and values
  • Presentation of fault currents with characteristic and duration
  • Reproduction of phase currents during the fault current surge
  • Presentation of the phase voltages during the fault current surge

Measuring device homepage

  • Webserver on the measuring device, i.e. device's own homepage
  • Remote operation of the device display via the homepage
  • Comprehensive measurement data incl. PQ
  • Online and historic data available directly via the homepage
  • Waveform representation of current and voltage

Ethernet (TCP/IP)- / Homepage- / Ethernet-Modbus gateway functionality

  • Simple integration into the network
  • More rapid and reliable data transfer
  • Modern homepage
  • World-wide access to measured values by means of standard web browsers via the device's inbuilt homepage
  • Access to measurement data via various channels
  • Reliable saving of measurement data possible over a very long periods of time in the 256 MByte measurement data memory
  • Connection of Modbus slave devices via Ethernet-Modbus gateway

Digitale IOs

  • Extensive configuration of IOs for intelligent integration, alarm and control tasks

Analysis of the harmonic fault current components

  • Frequencies of the fault currents (fault type)
  • Current peaks of the individual frequency components in A and %
  • Harmonics analysis up to 40th harmonic
  • Maximum values with real-time bar display

Highest possible degree of reliability

  • Continuous leakage current measurement
  • Historical data: Long-term monitoring of the residual current allows changes to be identified in good time, e.g. insulation faults
  • Time characteristics: Recognition of time relationships
  • Prevention of neutral conductor carryover
  • RCM threshold values can be optimized for each individual case: Fixed, dynamic and stepped RCM threshold value
  • Monitoring of the CGP (central ground point) and the sub- distribution panels

Extensive selection of tariffs

  • 7 tariffs each for effective energy (consumption, delivery and without backstop)
  • 7 tariffs each for reactive energy (inductive, capacitive and without backstop)
  • 7 tariffs for apparent energy
  • L1, L2 and L3, for each phase

Harmonics analyser / event recorder

  • Analysis of individual harmonics for current and voltage
  • Prevention of production downtimes
  • Significantly longer service life for equipment
  • Rapid identification and analysis of power quality fluctuations by means of user-friendly tools (GridVis®)

Energy measurement device

  • Continuous acquisition of the energy data and load profiles
  • Essential both in relation to energy efficiency and for the safe design of power distribution systems

RCM device

  • 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

Universal meter

  • Operating current monitoring for general electrical parameters
  • High transparency through a multi-stage and scalable measurement system in the field of energy measurement
  • Acquisition of events through continuous measurement with 200 ms high resolution
