3-Phase Power Measurement AC 480 V 1 A

The 3-phase power measurement module 750-494 enables the measurement of electrical data in a three-phase supply network. The voltage is measured via the network connection at the terminals L1, L2, L3, and N. The current of the three phases is fed through current transformers at the terminals IL1, IL2, IL3, and IN.

The preprocessing of the 3-phase power measurement module provides all measurement values such as reactive power, apparent power, active power, energy consumption, power factor, phase angle, frequency, as well as overvoltage and undervoltage, and overcurrent and undercurrent directly in the process image, without requiring high computational power on the controller. These extensive measurement values, along with harmonic analysis up to the 41st harmonic, enable a comprehensive network analysis to be conducted via the fieldbus. Based on the provided measurement values, the plant operator can optimize the supply of a drive or machine and protect the system from damage or failures. The 4-quadrant display indicates the type of load (inductive, capacitive) and whether it is a consumer or producer of energy.
