Power measurement AC/DC 277V external shunts. The power measurement module 750-494/000-005 enables the measurement of electrical data in a three-phase power 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 external shunts at the terminals IL1, IL2, IL3, and IN. The preprocessing of the power measurement module provides all measurement values such as reactive, apparent, and active power, energy consumption, power factor, phase angle, frequency, as well as over- and under-voltage and over- and under-current directly in the process image, without requiring high computing power on the controller. These extensive measurement values, along with harmonic analysis up to the 41st harmonic, enable a comprehensive network analysis 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.
