The scope of application of three phase electric meter and single phase electric meter is different

1. Three phase electric meter: three phase electric meter is suitable for measuring three-phase four-wire AC active energy with a rated frequency of 50Hz or 60Hz. For fixed installation indoors, suitable for the environment, and the air does not contain corrosive gas and avoid dust, mold, salt spray, condensation, insects, etc.

2. Single phase electric meter: It is suitable for commercial buildings and public infrastructure buildings to realize the measurement and statistics of the electric energy consumption of different areas or different loads in the building; it is suitable for the electric energy consumption statistics of different production lines or various loads in industrial buildings. Accounting.
