Many users buy electricity meters but do not know how to choose the electricity meter and the appropriate model specifications. This article has made detailed descriptions for different load power sizes, applicable occasions and electricity meter models. Everyone chooses the appropriate model specifications according to the power and load type.

①Load power: below 30KW (main load type: electric light, low-power air conditioner).
Application: facade or hand workshop.
Applicable power meter type: three-phase active energy meter (function requirement: active power metering), accuracy level 1
Description of functional requirements: Reactive loss is small, and simple active energy meters can be used.

② Load power: 30-60KW (main load type: electric lamp, electric heating equipment).
Application: facade or hand workshop.
Applicable power meter type: three-phase active energy meter (function requirement: active power metering), accuracy level 1
Description of functional requirements: There is no reactive power loss, and a simple active energy meter can be used.

③ Load power: 30-60KW (main load type: electric lamp, low-power air conditioner, electric heating equipment).
Application occasions: facade or hand workshop, workshop.
Applicable energy meter type: three-phase active energy meter or three-phase active and reactive energy meter (function requirements: active and reactive power measurement, reactive power measurement counts into positive electricity), accuracy level 1
Description of functional requirements: The total active power is not large, and active energy meters or active and reactive combined energy meters can be used.

④Load power: 30-60KW (main load type: air conditioner, electric motor, lathe).
Application occasions: industrial workshops, workshops.
Applicable electric meter type: three-phase multi-function electric meter or smart electric meter (function requirements: active and reactive power measurement, multi-functional and reactive power measurement included in the positive power), accuracy 0.5S level.
Description of functional requirements: no impact due to high power click load, you need to choose a multi-function energy meter, the measurement chip is highly sensitive.

⑤ Load power: 60-100KW (main load type: air conditioner, motor, lathe is not the main electrical load).
Application: workshop.
Applicable electric meter type: three-phase multi-function electric meter or smart electric meter (function requirements: active and reactive power measurement, multi-functional and reactive power measurement included in the positive power), accuracy 0.5S level.
Description of functional requirements: due to the larger power, a multi-function energy meter is required.

⑥ Load power: 60KW or more (main load type: air conditioner, motor, lathe).
Application: workshop, factory.
Applicable electric meter type: three-phase multi-function electric meter or smart electric meter (function requirements: active and reactive power measurement, multi-functional and reactive power measurement included in the positive power), accuracy 0.5S level.
Description of functional requirements: Due to the large power and the complex power waveform, a 0.5S multi-function ammeter is required.

⑦ Load power: 100KW or more (main load type: any load).
Application: factory.
Applicable electric meter type: three-phase multi-function electric meter or smart electric meter (function requirements: active and reactive power measurement, multi-functional and reactive power measurement included in the positive power), accuracy 0.5S level.
Description of functional requirements: Due to the large power and the complex power waveform, a 0.5S multi-function ammeter is required.

⑧ Load power: high voltage measurement (main load type: any load).
Application: High-pressure side of high-pressure device.
Applicable meter type: three-phase multi-function meter or smart meter (function requirements: active and reactive power measurement, multi-function), accuracy 0.5S level.
Description of functional requirements: Due to the large power and the complex power waveform, a 0.5S multi-function ammeter is required.

⑨ Load power: gateway measurement (main load type: any load).
Applications: power plants, substations.
Applicable power meter type: three-phase high-precision energy meter (function requirements: active and reactive power measurement, multi-function, reactive power measurement in each quadrant), accuracy 0.2S level.
Description of functional requirements: When measuring at the gate, a 0.2S precision meter is required.

⑩ Load power: gateway measurement (main load type: any load).
Applications: Intelligent power plants and substations.
Applicable electric meter type: three-phase high-precision electric energy meter (function requirement: full digital information input), accuracy 0.1S level.
Description of functional requirements: Smart grid requires the use of fully digital electric meters.
