<p>The 750-493 3-Phase Power Measurement Module measures the electrical data in a three-phase supply network.</p><p>The voltage is measured via network connection to L1, L2, L3 and N.</p><p>The current of the three phases is fed to IL1, IL2, IL3 and IN via current transformers.</p><p>The 750-493 Module transmits the root mean square values into the process image without requiring high computing power from the controller. For each phase, the effective power (P) and the energy consumption (W) are calculated by the module using the root mean square values for all measured voltages (V) and currents (I). For example, both the apparent power (S) and phase shift angle (φ) can be easily derived from these values.</p><p>Therefore, the 750-493 Module provides comprehensive network analysis via fieldbus. Metrics, such as effective and apparent power consumption or load condition, enable the operator to optimize supply to a drive or machine. This can protect the installation from damage and failure.</p>
