The LINAX^® PQ5000CL enables certified power quality and performance analysis with up to 32 conductors in low-voltage sub-distribution. Current Link technology is used to centrally record current values via a measuring device; the Rogowski sensors are networked in a scalable ring circuit. This reduces installation costs and ensures neat cable routing. The system is metrologically certified and complies with the standards IEC 60688 (transducer), IEC 61557-12 (power metering), and IEC 62586-1 (power quality).

• PQ5000CL measuring instrument (PQ5000 with Current Link expansion)

Further properties

• Metrologically certified PQI according to IEC 61000-4-30 Ed. 3 class A as basic device
• A scalable system for certified power quality as well as load and efficiency management for up to 10 channels (32 conductors)
• Monitoring of outgoing circuits with 3 or 4 currents with 3P/3PN Current Link modules (max. 32 currents)
• Simultaneous measurement of multiple outlets instead of traditional per-outlet measurement
• Direct conformity reporting and event display through PQEasy reporting via web browser (e.g. in accordance with EN 50160)
• Fault recording of voltage events, optionally with the time-synchronized currents of the reference channel
• Time-synchronized load management for U/I/P/Q/PF
• 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 (supply & demand)
• System management via a user-friendly multi-device tool for simple commissioning and efficient maintenance
• Low space requirement & low wiring effort based on the scalable current sensors
• It is not necessary to shut down the system to install the measuring system due to the non-invasive Rogowski measuring technology
• Very high robustness due to proven coaxial principle
• Current values are time-synchronized with the voltage (IEC 61000-4-30)
• Open communication system enables high connection flexibility to both parallel and higher-level systems
• Very fast installation with robust measurement technology
• Sampling rate of the currents 54 kHz
