Item description
The 750-495 3-Phase Power Measurement Module measures electrical data in a three-phase supply network. The voltage is measured via network
connection to L1, L2, L3 and N. The current of the three phases is fed to IL1, IL2, IL3 and IN (two clamping points each +,-) via current transformers
or via Rogowski coils for the 750-495/000-002 module. The 750-495 Module transmits metrics (e.g., reactive/apparent/effective power, energy
consumption, power factor, phase angle, frequency, over-/undervoltage) directly into the process image, without requiring high computing power
from the controller. Both comprehensive metrics and harmonic analysis up to the 41st harmonic permit extensive network analysis via the fieldbus.
Metrics allow the operator to optimize the supply to a drive or machine, protecting the system from damage and failure. Insulation failures can be
detected and prevented via current measurement performed in the neutral conductor. The 4-quadrant display indicates the type of load (inductive,
capacitive) and whether it is an energy consumer or producer.
