1 System Description

Electricity meter systems consist of multiple parts such as sensors, ADC, MCU, power supply, and communication. The three main components of an electricity meter are current sensing, data acquisition, and metrology engine. This design guide provides a better understanding of the main parts of an electricity meter, how to put them together, and how to evaluate and use the reference design.
