PQI-DE
Power Quality Network Analyser voor paneelmontage
The Power Quality Analyser and Fault Recorder PQI-DE for low, medium and high voltage networks is the central component of a system with which all measurement tasks in electrical networks can be solved.
The PQI-DE can be used as a Power Quality Interface according to power quality standards such as IEC 61000-2-2 / EN 50160 or to check the technical connection guidelines such as DIN VDE AR 4110 and DIN VDE 4120 and many more.
Due to the available open SCADA standard interfaces such as Modbus RTU/TCP as well as IEC 61850 with open data exchange format PQDIF (IEEE1159-3), the device can also be used as a highly accurate measurement transducer for all physically defined measured variables in 3-phase systems parallel to the continuous recording of measured values over a very long period. In addition to the possibility of standard evaluations, the PQI-DE also has a high-speed disturbance recorder with a recording rate of 40.96kHz/10.24kHz and a 10ms TRMS effective value recorder. This allows a detailed evaluation of grid disturbances.
The PQI-DE is equipped with a fifth current input for continuous residual current monitoring (RCM).
It is possible to freely program thresholds for alarms or warnings.
Modern Power Quality Analysers comply with the IEC 62586 standard, which describes the complete product feature of a Power Quality Analyser. This standard defines not only the purpose of use, the EMC environment and the environmental conditions, but also the exact measurement methods IEC 61000-4-30 Class A, in order to create a comparable and reliable basis for the end-user. Devices from different manufacturers that work according to this standard must provide the same measurement results.
According to IEC 62586, the PQI-DE is a device of class PQI-A-FI-H and is therefore fully certified in external laboratories. Power Quality Interface – Class A – Fixed Installed Measurement Device for Indoor operation in Harsh EMC environments.
The PQI-DE meets the requirements of IEC 61000-4- 30:2015 Ed 3 +A1:2021 for Class A measuring instruments for 100 % of the parameters.
