Power Quality Analyser and Fault Recorder PQI-DE

 

Application:

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 IEC61000-2-2 / EN50160 or to check the technical connection guidelines / gridcodes.

The PQI-DE has been developed for measurements performed within public grids, for Smart Grid applications, as well as for recording PQ-data within an industrial environment up to 690V (L-L) measurement voltage. It also allows frequency measurement of voltage and current harmonics according to IEC 61000-4-7 from 2 kHz to 9 kHz.

Due to the available open SCADA standard interfaces such as Modbus RTU/TCP as well as IEC 61850, 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 of time.

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. (prepared)

Modern Power Quality Analyzers comply with the IEC 62586 standard, which describes the complete product feature of a Power Quality Analyzer. 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 adn 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 AFixed Installed Measurement Device for Indoor operation in Harsh EMC environments The PQI-DE meets the requirements of IEC 61000-4-30 Ed.3 (2015) for Class A measuring instruments for 100% of the parameters.
