Measurement, Evaluation and Reporting of Your Power Quality Measurement Data and Fault Records
Simple, Safe, Fast
Optimized Analysis and Reports
Detection of faults in seconds
What is the current grid status? Where were the last faults? Which measuring devices have the most power quality events?
With the new Power Quality Software WebPQ® you never lose track of your grid and can create individual reports from over 60 templates for all relevant national and international standards & grid codes as required.
- Fleet analysis: identify faults and trends at the click of a mouse
- Customized reports: Create reports from over 60 templates for common standards & grid codes
- Automatic monitoring: you can create regular, individual reports/status reports and limit value warnings in no time at all
- Fast fault detection with immediate alarm in the event of faults: Efficient problem analysis and solution
Analysis Section
Get to the bottom of the causes of grid faults individually
With WebPQ® you can configure your own analysis dashboard - according to your wishes and requirements. Benefit from a particularly efficient analysis of your relevant grid status and power quality parameters.
- Choose your desired representation from a large selection of different diagram types (click/swipe through the diagram representations)
- Freely select the displayed devices and measured variables (e.g. voltage, power or energy consumption)
- Easily display multiple devices and time ranges per analysis
- Your analysis dashboard can be saved individually for each user and application
- Quickly and easily share your analyses with your team using the “Share” functions (exportable as .pdf and in common image formats)
Device View
Get a quick overview of an individual measuring point/device with historical data, live data and as a power quality report
- Historical Data:
- Faults and PQ events classified by duration and depth using an interactive ITIC curve
- Voltage extremes, THD and flicker as level time diagrams
- List of all fault records with details of duration and depth
- Frequency as an interactive histogram dashboard
- Live-Data:
- Oscilloscope
- Level-time diagram of all data classes
- Harmonic evaluation
- Power Quality Report
- Automatic generation of standard-compliant PQ reports (> 60 pre-installed standard & grid code templates)
- Clear visualization of limit violations and key PQ parameters
- Export function as PDF or CSV for further processing and documentation

The New Power Quality Software for Continuous Grid Monitoring
Efficient Device and Fleet Management
Everything at a Click
WebPQ® allows you to manage and monitor a large number of measuring devices simultaneously. In addition to central fleet management, remote firmware updates are also possible. This saves you effort and valuable resources.
- Device management: Categorize your measuring devices hierarchically or flexibly using device tagging
- Fleet management: Roll out templates & firmware simultaneously across your entire device fleet
- Template management: Manage your templates easily and comprehensibly with versionable parameters
- Remote firmware updates: Firmware patches can be carried out remotely, minimizing risks and saving time
Open and Flexible Data Management
Transfer measurement data openly, easily and securely to the interfaces in your company
We know how important it is that your data can be passed on transparently via standard interfaces to third-party software such as network calculation tools or other applications easily and in full.
Among other things, the software also offers a fully configurable REST API documented via Swagger.
- REST API: Open for versatile applications and customizations
- Data export: Manual or automatic in formats such as CSV, NeQual, Comtrade and PQDIF
- Data import*: Seamless processing of CSV, Comtrade and PQDIF
- Compatibility: Easy integration of measurement data from mobile devices*
*higher versions
Safe and Secure!
IT security with full user rights management system (user administration) with role-based access control and rights management (RBAC)
Assign read or write permissions for devices or groups of devices simply, securely and quickly via central user administration.
- Maximum security: URM and RBAC offer flexible access control
- Encrypted communication: HTTPS and own certificate management
- Simple integration: Seamless connection to LDAP systems*
- Full transparency: audit logs for every access and every change
