The accurate measurement of carbon steel tee pair power consumption is based on the electromagnetic induction method to obtain the offset matched by the accurate measurement. The typical dashboard of this link is the electromagnetic induction galvanometer, carbon steel tee which is based on the rotating force of the current through the electromagnetic coil in the electromagnetic field, and the size of the current is expressed by the deflection of a needle driven by this force.
Therefore, on the carbon steel tee, the size of the needle deflection can reflect the size of the current passing through the electromagnetic coil. Basically, in the electromagnetic induction galvanometer, according to converting other quantities into current, we can accurately measure other quantities of electricity, such as converting working voltage into current according to resistor, we can turn carbon steel tee into voltmeter, and converting frequency into current according to different impedance of capacitor to different frequency characteristics. And carry out accurate frequency measurement and so on.
