Power Quality Measurement

Power quality measuring systems

Power Quality Measurement

Power quality measurement = EPPE

Power quality measuring systems with integrated fault recorder functionality for continuously and automatically monitoring electrical installations at all voltage levels. The measuring systems of the EPPE series continuously and precisely record all the electrical parameters of the power supply. They deliver detailed quality evaluations which reveal even the smallest of deviations and contribute to identifying the cause of disturbances

EPPE power quality analysers

Whatever processes are currently underway in a power system, the power quality analysers of the EPPE series will register even minor disturbances or alterations. Detailed quality evaluations reveal even the slightest of deviations and help identify the cause of disturbances.

EPPE systems continuously capture all power system parameters for the analysis and documentation of power quality to standards defined by the international standards such as EN 50160 or IEC 61000-4-30. High storage capacities and effective data compression methods enable long-term recordings to be made over periods of up to several years.

As well as continuously recording all the quantities relevant to power quality, the integrated fault recorder module allows the event-triggered capture of transient processes with sampling rates of up to 30 kHz.

Fields of application:

  • PQ measurement to EN 50160
  • Residual current monitoring
  • Professional fault recorder
  • Energy meter and power analyser
  • Frequency analyser
  • Trend and long-term data logger
  • IEC 61850, IEC 60870-5-103, Modbus

Examples of applications:

  • Power quality monitoring to EN 50160
  • Differential current measurement
  • Acquisition of power data and load profiles
  • Optimisations of power use
  • Transient recorder for detailed fault analysis
  • Identification and recording of power swings
  • Acquisition of closing and opening operations
  • Measurement of flicker and harmonics
  • Monitoring and analysis of renewable power systems
  • Network optimization
  • Load management
  • Fault location
  • Trend recording
  • Critical load monitoring
