​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.

Má fhaightear amach gur méadar uaire saor ó luaidhe nó vata imithe in éag é, iarr ar an roinn ábhartha a-chalabrú sula n-úsáidtear é chun an leictreachas a thomhas go beacht. .

​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
