PowerTech System Trading LLC



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



• 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)
• Simultaneous measurement of multiple feeders instead of traditional per feeder measurement
• Direct compliance reporting and event display by PQEasy reporting via web browser (e.g. according to EN50160)
• Time-synchronous fault recording of voltage events with currents of the individual channels (IEC61000-4-30 Ed. 3)
• Time synchronous load management for U/I/P/Q/cosφ
• Current measurement per Current Link channel «IN1 (typical/maximum) of 400 A / 1’000 A» and «IN2 (typical/maximum) of 8’000 A / 20’000 A»
• Grid tariff meter P & Q (purchase & delivery)
• System management by means of a user-friendly multi-device tool for easy commissioning and efficient maintenance
• Low space requirement due to single voltage measurement
• No need to shut down the plant for installation of the measuring system due to the non-invasive Rogowski measuring technique
• Very high robustness due to proven coaxial principle
• Current values are time synchronous to voltage (IEC61000-4-30)
• 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
• Fast roll-out with robust measurement technology
• Sampling rate 54 kHz (zero blind technology)

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
