Power quality analysers

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:

  1. PQ measurement to EN 50160
  2. Residual current monitoring
  3. Professional fault recorder
  4. Energy meter and power analyser
  5. Frequency analyser
  6. Trend and long-term data logger
  7. IEC 61850, IEC 60870-5-103, Modbus

Examples of applications:

  1. Power quality monitoring to EN 50160
  2. Differential current measurement
  3. Acquisition of power data and load profiles
  4. Optimisation of power use
  5. Transient recorder for detailed fault analysis
  6. Identification and recording of power swings
  7. Acquisition of closing and opening operations
  8. Measurement of flicker and harmonics
  9. Monitoring and analysis of renewable power systems
  10. Network optimisation
  11. Load management
  12. Fault location
  13. Trend recording
  14. Critical load monitoring
