1. one kind can be reduced the electronic electric energy meter that alternating electromagnetism disturbs, and comprises the circuit board of shunt, relay and electronic electric energy meter;

  • Described shunt is connected to an exit of relay;

    Shunt is the sheet body structure, contains one section sampling resistor sheet that adopts high resistivity material to be made in the shunt, and the two ends of sampling resistor sheet are connected to respectively the circuit board of described electronic electric energy meter by signal wire;

    It is characterized in that;

    described sampling resistor sheet is set as bending structure, so that the sampling resistor sheet is becoming less perpendicular to the projected area of the magnetic direction of disturbing magnetic field with respect to the projected area of original plane-shaped structure.
