In a single-phase AC (sinusoidal) system, under voltage U [V], I [A] current draw and power coefficient kgk To measure the power drawn by a load, an active power W- with the relevant steps “UNW=2U, INW=I/4” meter will be used. Measuring by specifying the appropriate characteristics for the additional elements required Draw the entire circuit diagram. According to the diagram you have drawn, the pointer of the W-meter is If it deviates by one tenth, calculate kgk.
