LINAX® PQ5000CL

Power quality assessment with modular load flow information for grid level 7 (low voltage).

Area of Application

  • Monitoring of the feed in substations
  • Monitoring of industrial power distribution systems
  • Energy optimization through identification of load behavior
  • General smart grid applications

Features

  • Metrologically certified PQI according to IEC61000-4-30 Ed. 3 class A as basic device
  • A scalable system for the areas of certified power quality as well as for load and efficiency management for up to 10 feeders
  • An optional basic current measurement (e.g. directly after the transformer) with a high accuracy due to current transformer sensors
  • 3 or 4 channels via Current Link per feeder (max. 32 currents)
  • One measurement campaign time-synchronized for multiple feeders as opposed to the traditional measurement campaign per feeder
  • Direct compliance reporting and event display by PQEasy reporting via web browser (e.g. according to EN50160)
  • Time-synchronousfault recording of voltage events with currents of the individual channels (IEC61000-4-30 Ed. 3)
  • Time synchronousload management for U/I/P/Q/cosφ
  • Current measurement per Current Link channel up to 1’000A and overcurrents up to 20’000A
  • Network tariff meter P & Q (purchase & delivery)
  • Upgrade to control task in smart grid (e.g. PQ grid utilization)
  • System management by means of a user-friendly multi-device tool for easy commissioning and efficient maintenance
  • Large distribution systems (feeders) are continuously monitored with only one metrologically certified measurement system
  • Low space requirement due to single voltage measurement
  • Low wiring effort based on the scalable current sensors
  • No need to shut down the plant for installation of the measuring system due to the non-invasive Rogowski measuring technique (Attention: observe occupational health & safety)
  • Very high robustness due to proven coaxial principle
  • Current values are time synchronousto voltage (IEC61000-4-30)
  • Optional fault recording in case of short circuit
  • Various communication interfaces (Modbus TCP/IP, Modbus RTU, REST API, IEC61850, Cloud with MQTT, Webbrowser) allow high connectivity flexibility to parallel as well as higher-level systems
  • Multilingual
  • Fast roll-out with robust measurement technology
