3 Phase Power Measurement; 690 VAC Rogowski coils; Light greyThe 750-495 3-Phase Power Measurement Module measures electrical data in a three-phase electrical network. Voltage is measured via mains connection L1, L2, L3 and N. Three-phase current is fed to IL1, IL2, IL3 and IN (two clamping points +,- each) via current transformers. The 750-495 Module sends metric values (e.g. reactive/apparent/effective power, energy consumption, power factor, phase angle, frequency, over/under voltage) directly to the process image without requiring high processing power from the controller. Both comprehensive metric values and harmonic analysis up to the 41st harmonic provide extensive network analysis via fieldbus. Metric values enable the operator to optimize the supply to a drive or machine, protecting the system from damage and failure. Insulation faults can be detected and prevented by measuring current in the neutral conductor. The 4-quadrant display shows the load type (inductive, capacitive) and whether it is energy consuming or producing.
