How To Choose The Capacity of Household Electricity Meter？(1)

Our current household watt-hour meters are all active watt-hour meters, which record the active energy consumed by electrical appliances, and do not record reactive energy. So how much A is suitable for a household electric meter? How big of an electric meter should a home install? Generally, the rated current of household electric meters should not be greater than 10 amps. The specific situation will also be determined according to the needs. Below, we will introduce the capacity selection and installation of some household electric meters.

Introduction of Electricity Meter:

Electric energy meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, kilowatt-hour meter, refers to the instrument for measuring various electrical quantities, commonly known as watt-hour meter, fire meter.

By use: industrial and civil meter, electronic standard meter, maximum demand meter, multi-rate meter

According to the structure and working principle: induction type (mechanical type), static type (electronic type), electromechanical integrated type (hybrid type)

According to the nature of the access power supply: AC meter, DC meter

According to the accuracy level: commonly used ordinary tables: 0.2S, 0.5S, 0.2, 0.5, 1.0, 2.0, etc.

Standard table: 0.01, 0.05, 0.2, 0.5, etc.

According to the installation wiring method: direct access type, indirect access type

According to electrical equipment: single-phase, three-phase three-wire, three-phase four-wire electric energy meter.
