A shunt is a small electrical device that carries a current between two points. The shunt is often connected to a single-phase meter. Unlike a meter, a shunt does not carry the same amount of current as a single phase meter, but it is useful for determining the amount of current flowing from one location to another. Shunts can be used for multiple locations, such as the alternator output.
Energy meters can either add up or integrate the value of instantaneous power to compute the total energy used during a period. This type of meter is also known as a power factor compensator. It works by rotating a small disc with a speed proportional to its power. As a result, the shunt and series magnets induce eddy currents in the aluminum disc. The eddy currents induce driving torque within the disc, which is proportional to the amount of energy consumed by the load during the time interval. The energy is normally measured in kilowatt-hours.
Shunt magnets are made of a fine wire with many turns connected across the supply voltage. This coil is highly inductive, so the flux lags behind the supply voltage by a 90-degree angle. A series magnet, on the other hand, is made from a heavy wire with only a few turns. The voltage generated by the shunt is proportional to the current of the load, so the angle of the lag is 90 degrees.
