Digital Energy Meter: Extensive Applications Across Multiple Fields

A digital energy meter is a device used to measure electrical energy, also known as an electricity meter or kilowatt-hour meter. It measures the accumulated energy consumption over a specific period and is commonly used to record and display electricity usage.

Digital energy meter can be categorized based on their structure and working principles into electromechanical (induction) digital energy meters and electronic digital energy meters. Based on accuracy levels, they can be classified into general-purpose and standard meters, with general-purpose meters used for daily measurements and standard meters primarily used for calibrating general-purpose digital energy meters. According to their application, digital energy meters can be divided into active energy meters, reactive energy meters, maximum demand meters, multi-rate energy meters, multi-function energy meters, and prepaid energy meters.
