What is a Three Phase Energy Meter?
Understanding the Basics of a Three Phase Energy Meter
A three-phase energy meter is a meter that measures the electrical energy consumed in a three-phase power system. They are typically found in industrial and commercial enterprises, or even in larger homes where considerable power consumption takes place. Unlike single-phase energy meters intended for use within small homes, three-phase meters can accommodate greater loads, aiding in the control of energy monitoring and management in advanced electrical systems. These meters connect to the three supply phases, where phase A, phase B, and phase C are accessible. Thus, these meters provide in-depth information with regards to power usage, phase balance, and energy distribution in a given system.

How does a 3-phase energy Meter work?
A three-phase energy meter works by measuring power on all three phases of a system. It calculates active, reactive, and apparent power consumption as well as energy used over time. For measuring voltage of the system, the meter has sensors such as current transformers (CTs) for current measurement and Potential Transformers (PTs) for voltage measurement. The meter calculates the value on all three phases to give the best value for energy consumed. Digital meters offer even more functionality by providing energy monitoring, data logging, and connections to advanced management systems. Also, these digital meters allow multifunctional management and a better understanding of power usage.
