Records transients at up to 24 µs
Transients are increasingly a problem in electrical grids. The PQI-DA smart offers the ability to measure these transients exactly down to 24 µs, allowing precise network analysis. Analysis with our device makes the grid not only more stable but also safer.

Fulfil the measurement standards of tomorrow today
Our fix installed all-rounder offers a wide range of measurement options that represent the standards of tomorrow, today. Thus, our PQI-DE power quality device already provides frequency measurement from 2 – 20 kHz. Consider buying one of our devices as investing in the solutions of the future.
Residual current measurement RCM to 40.96 kHz over 5 current channels
Residual current measurement has a wide range of applications. On the one hand, the measurement device can be used to substitute repeat insulation tests to DIN VDE 0150-100/A1; while in connection with a switch-off device it can also provide fire and material protection. The PQI-DE is the first device in the product portfolio that can do both.
IT security from the manufacturer with ISO 27001 certification
Certified security via User Rights Management (URM) and Role Based Access (RBAC) thanks to highly encrypted data transmission.

Power quality monitoring with »PQI-DE« in combination with »I-Sense«
High-quality power quality monitoring with the option of quick and easy feeder current measurement helps to recognise trends at an early stage and enables countermeasures to be initiated at the right time.
High-precision transformer measurement with »PQI-DA smart« or »PQI-DE«
- Measure voltage, current and power quality parameters at the transformer feed-in with a deviation of less than 0.1% in accordance with IEC61000-4-30 Class A Ed. 3 to evaluate the power quality via in accordance with EN50160 and IEC61000-2-2.
- Analysis of flicker, THD, harmonics (H2-H50), supraharmonics 2-20kHz, transients & PQ events with fault recording.
Measuring, recording and analysing outgoing circuits with the »I-Sense« current measurement technology
- Current measurement L1/ L2 / L3 / (N) with min. and max. values for up to 16 feeders.
- Simple connection possible using existing third-party devices, such as switching pannels with intelligent transducers.
Reporting – to the point with the »WinPQ« & »WebPQ« analysis software
- WinPQ software for quick and easy evaluation of power quality and feeder current using intuitive, configurable reports. Click here for an example report!
