Software platform

GridVis — power quality analysis and reporting software

GridVis is Janitza's power quality analysis and reporting software — processing compliant measurement data captured by Janitza instruments to provide structured analysis, visualisation, and reporting across all major power quality parameters.

GridVis works directly with Janitza's Class A analysers and multifunction meters — enabling real-time monitoring, historical analysis, event logging, and automated generation of compliance reports. The compliance capability is rooted in the measurement accuracy of Janitza instruments; GridVis structures and presents that data in report formats aligned with international standards.

GridVis

Power quality analysis and reporting platform — on-premise and cloud-based deployment

✓ Real-time power quality monitoring and dashboards

✓ Historical data storage and trend analysis

✓ Event recording, waveform capture, and disturbance logging

✓ Automated compliance report generation — IEEE 519, EN50160

✓ Harmonic spectrum analysis up to 63rd order

✓ Multi-device, multi-site centralised monitoring

✓ On-premise server or cloud-based deployment

✓ Web-based access and remote monitoring capability

GridVis report outputs are based on measurement data captured by Janitza instruments — compliance reports are only as accurate as the instruments generating the underlying data. Class A instruments such as the UMG 512 ensure measurement data meets the requirements of IEC 61000-4-30.

Key instruments

Janitza power quality instruments

From Class A analysers to multifunction energy meters — Janitza offers a wide range of instruments covering every level of power quality and energy monitoring requirement.

Class A Analyser IEC 61000-4-30 IEEE 519 EN50160

UMG 512 PRO

Janitza UMG 512

The UMG 512 PRO is Janitza's flagship Class A power quality analyser — compliant with IEC 61000-4-30 Class A, the highest classification for power quality measurement instruments. This classification ensures that measurement results are accurate, reproducible, and suitable for compliance verification, regulatory reporting, and legal disputes.

The UMG 512 is the instrument of choice for Power Quality Measurement Systems where compliance with IEEE 519, EN50160, and IEC 61000 series standards needs to be demonstrated — providing the measurement foundation that GridVis uses to generate structured compliance reports.
