Alternating current power meter, K. Szpotański

The consumption of alternating current received from the grid by the customer can be measured using induction meters, among other methods. Of those that still remain in production, it is the oldest type of metering device for the measurement of the consumption of alternating current in kilowatt-hours. The device works as follows: two coils are connected to electricity and generate a magnetic field that sets an aluminium disc in motion. The disc is connected to a drum mechanism that allows the meter to be read. In this case, the amount of electrical energy consumed is proportional to the number of rotations of the disc under the influence of the field generated by the coils. The three-phase induction meter presented here was made in the FAE production facility in Warsaw. It was established in 1918 by Kazimierz Tadeusz Szpotański.
