A fiscal electricity meter is described for measuring the energy supplied to a load. The load current flows 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 sense coil, arranged to couple more strongly to the primary, and a cancellation coil which have equal and opposite turns area products so as to provide a null response to extraneous magnetic fields. The coils are arranged so that their magnetic axis are co-located and aligned together so that they also provide a null response to extraneous magnetic fields having a field gradient.

L'invention concerne un capteur d'électricité affichant les coûts qui permet de mesurer l'énergie fournie à une charge. Le courant de charge circule à travers un enroulement primaire d'un transformateur et induit une FEM indiquant la circulation du courant dans l'enroulement secondaire. Ce dernier comprend une bobine de détection, conçue de façon à épouser plus fermement l'enroulement primaire, et une bobine de suppression ayant des produits de secteur à spires égales et opposées de façon à produire une réponse nulle à des champs magnétiques extérieurs. Les bobines sont disposées de façon que leurs axes magnétiques soient côte à côte et alignés afin qu'ils produisent également une réponse nulle aux champs magnétiques extérieurs ayant un gradient de champ.
