| Abstract: | A non-contact method to measure electric current through the electric net by using Hall sensor is put forward. The mathematical model for measuring heavy current is deduced in theory.With three-circuit transmission in parallel, the metrical project can be established. The circuit structure of sensor part is verified,scale conversion and digital display is realized by single chip computer. |
