Areas of application

• Measurement, monitoring and checking of electrical characteristics in energy distribution systems
• Recording of load profles in energy management systems (e.g. ISO 50001)
• Acquisition of the energy consumption for cost centre analysis
• Measured value transducer for building management systems or PLC (Modbus)
• Monitoring of power quality characteristics, e.g. harmonics up to 40th harmonic
• Residual current monitoring (RCM)
 

Main features

Universal meter

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

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

Energy measurement device

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

Harmonics analyser / event recorder

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

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

Highest possible degree of reliability

• Continuous leakage current measurement
• Historical data: Long-term monitoring of the residual current allows changes to be identifed 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 subdistribution panels

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
