​This meter is used to measure the three-phase four-wire AC active energy with a rated frequency of 50HZ and a reference voltage of 3220/380V.

Si yo jwenn li se yon mèt plon-gratis oswa ekspire mèt watt-èdtan, tanpri mande depatman an ki enpòtan pou re-kalibre anvan enstale ak lè l sèvi avèk li asire mezi egzat nan elektr

​In low-voltage three-phase four-wire lines, three-element three-phase watt-hour meters are commonly used. If the load current on the line does not exceed the range of the watt-hou
