| description | The invention discloses a method and a device for determining current abnormity of an intelligent electric energy meter and computer equipment, relates to the technical field of electric energy metering, and solves the problems that a current fault of the intelligent electric energy meter cannot be directly positioned and the fault processing efficiency is relatively low at present. The method comprises the following steps: determining a voltage phasor diagram based on a voltage positive phase sequence of the intelligent electric energy meter, and in the voltage phasor diagram, determining a current phasor # imgabs1 # of a first element by taking a first element voltage # imgabs0 # as a reference, and determining a current phasor # imgabs2 # of a second element by taking a second element voltage # imgabs2 # as a reference; and determining the current phasor # imgabs3 # of the second element to calculate the b-phase secondary current # imgabs4 # of the intelligent electric energy meter, calculating the B-phase |
