What is the function of a power analyzer?

A power analyzer is specifically designed to record and analyze the electrical power consumption at a facility or load. It measures various parameters related to electrical energy usage, such as voltage, current, power factor, active power, reactive power, and apparent power. This information is crucial for understanding the efficiency of electrical systems, identifying energy-saving opportunities, and ensuring compliance with operational standards.

By measuring the power at a facility or load, the power analyzer provides valuable data that can be used to optimize energy usage, troubleshoot issues, and enhance the overall performance of electrical systems. While other options discuss important aspects of electrical systems, they do not define the primary role of a power analyzer, which is fundamentally about power measurement and analysis.
