Software for operation and evaluation

The ergonomic software designed in accordance with the Windows Fluent concept is designed to meet real-world requirements and can be put to a wide variety of different uses, ranging from the operation of an individual measuring device to the  administration of complex groups of EPPE measuring devices. There are 3 versions of the software which differ in functionality and in the number of measuring instruments to be managed.



”Basic” EPPE operating software

  • Functionality limited to power quality measurements in compliance with valid standards
  • Management of up to 5 EPPE measuring instruments

”Professional” EPPE operating software

  • Full range of functions
  • Management of up to 5 EPPE measuring instruments

”Premium” EPPE operating software

  • Full range of functions
  • Management of an unlimited number of EPPE measuring instruments

EPPE software for operation and evaluation is included in the scope of delivery of EPPE PX and features a full range of functions for managing one measuring instrument.

All versions of the software are very user-friendly and feature a variety of functions, including the following:

  • Flexible configuration for optimum customization to a wide range of measurement tasks
  • Remote configuration/administration
  • Fully automatic operation of the measuring system with
  • Remote data transmission
  • Archiving of records in a database
  • Printout or dispatch of fault reports and PQ quality reports
  • Export in common PQ and fault record formats
  • Online monitoring
  • Easy-to-use analysis tool with automatic evaluation and assessment of power quality to international standards (e.g. EN 50160)
  • Can be used with more than one screen (optimum overview, a wealth of information at a glance)

Device management

The operating software allows the connection and management of a large number of EPPE measuring devices.

The status information for all connected devices is displayed in a clearly structured device list, device settings can be adjusted quickly and easily.

In addition, graphical device management allows measuring devices and their status information to be displayed in a map, for example. This provides the user with an optimum overview of all measurements, even in comprehensive monitoring systems.

Online monitoring

All measured or calculated quantities can be called up online and displayed on a PC without affecting the data recording which is currently in progress. The measurement values can be combined within display windows, rather as in a control centre system. In addition to numerical display, the system also provides a range of graphical options, including analog pointer instruments, vector diagrams, bar graphs and oscilloscope displays.


The practical configuration module takes the actualities and requirements of modern power supply systems into account.

Templates which correspond to specific standards (e.g. EN 50160) can be selected for long-term recording and event analysis, so even users without specialist knowledge can conduct a full analysis of a power system. Recording parameters, such as the averaging interval or the selection of variables, can also be configured manually for customized power system analysis.

When using the fault recorder functionality, a wide range of parameters can be selected freely, including for example the sam-pling rate, recording duration, pre-fault and post-fault period and the variables for which triggers are to be defined.

Configuration options such as trigger inhibit, retrigger inhibit or trigger delay are available.

It is also possible to create logical links with the analog and binary measurement signals, providing monitoring options for PV plants or wind power plants, for example.

Power system quality analysis

Power system and power quality analysis can also be carried out automatically to the selected standard (e.g. EN 50160). A number of analysis tools are provided for this purpose:

  • Slow changes with trend analysis
  • Event recording with signature display
  • Flicker analysis
  • Harmonic analysis
  • Analysis of interharmonics
  • Event classification and assessment (UNIPEDE, ITIC, etc.)
  • Graphical display of extreme value duration distribution
  • Table overview of limit value violations
  • User-defined limit value and analysis settings
  • Automatic generation of weekly, monthly, quarterly and annual reports
  • Calculation and signal display for differential current measurements
  • Useful zoom functions and variable scaling
  • Superimposition of different signal characteristics
  • Formulary and formula editor for the calculation of further power system quantities

Evaluation of fault records

The software also contains a comprehensive range of powerful analysis tools for the assessment of fault records:

  • Vector displays
  • Harmonic analysis on the basis of full waves or to IEC 61000-4-7 with interharmonics
  • Freely configurable absolute and delta measurement cursors
  • Useful zoom functions and variable scaling
  • Simultaneous display, superimposition and synchronization of more than one fault record
  • Formulary and formula editor for the calculation of further power system quantities
  • Individual report creation using the clipboard
  • Automatic report creation

Mathematical signal analysis

A formula editor can be used to make further mathematical calculations within recordings. The results are added to the long-term record or the fault record as an additional signal.

Data formats

Import and export functions enable data to be exchanged between different systems using standard PQDIF, COMTRADE, CSV and XML (Nequal) file formats.
