A Current detector which comprises a Freight driver, which generates a magnetic field detector, a Winding and CompensationTo generate a Signal indicative of the Output Current on the basis of the difference between signals generated by the coils; and an Electricity meter which includes a Power detector.

摘要

This Invention describes a fiscal Electricity meter for the Measurement of the Energy supplied to a load.The LOAD CURRENT flowing through the primary Winding of a Transformer and induces an EMF indicative of the current Flowing In the secondary winding.The secondary Winding comprises a Coil detector, arranged to couple more strongly to the primary,Cancellation and a Coil that has products or areas of equal and opposite rotation Laps so that foresees an invalid response to Magnetic Fields Strangers.The coils are arranged so that their axes are aligned magnetic and cosituados together so that also provide a null response to Magnetic Fields which have a Strange ingRediente Field.
