What does a multi-function power meter measure in a 3-phase system?

A multi-function power meter in a 3-phase system is designed to provide a comprehensive view of the electrical performance of the system. It measures a variety of parameters crucial for analyzing and optimizing energy use and system stability. The correct answer includes voltage, current, power, power factor, and energy consumption, which are essential metrics when assessing a 3-phase electrical system.

Voltage and current readings help determine the electrical loads and their operational status. Power measurements provide insight into the real and reactive power being consumed, which is important for understanding the efficiency of the system and its performance under different loading conditions. The power factor indicates how effectively the electrical power is being converted into useful work, which is vital for identifying any issues with system efficiency. Energy consumption measurements track overall energy use over time, which can inform billing and operational decisions.

A broader range of metrics enables more effective monitoring and management of energy in industrial and commercial applications, allowing for improved energy efficiency and cost savings.
