»I-Sense« – bring maximum transparency to your grid
Monitoring the asset »secondary substation«
Transformer measurement according to 61000-4-30 Class A Ed. 3 incl. supraharmonics (2-20khz) and high-resolution fault recording in the event of a fault.
Economical and reliable
Three- or four-phase systems with up to 16 feeders can be realised economically.
High
compatibility
Compatible with our existing fixed installed power quality analysers PQI-DA smart & PQI-DE thanks to open interfaces (with feature P3 – Modbus gateway for I-Sense).
Easy to install and integrate
Quick, easy and secure installation on site via rogowski coils. Less wiring effort thanks to the daisy chain principle using standard RJ45 cables – especially for retrofit.
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.
Transparency in the distribution grid – powered by A. Eberle
Power quality monitoring with feeder current measurement technology
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.
Measure, record and analyse feeders with »I-Sense«
- 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
- WinPQ software for quick and easy evaluation of power quality and feeder current using intuitive, configurable reports. Click here for an example report!
