Abstract

A new type of direct current sensor was studied which includes magnetic potential self-balance circuit and feedback compensation circuit. The characteristics of the device are simple construction, good stability and reliability, and high precision. A simulation model for new direct current sensor is developed. The simulation results of the system have indicated that the accuracy of the DC sensor is better than 0.1%. The enough experiments have carried on. The currents of balance winding and compensation winding are sampled separately at first. Then the current is sampled after adding the currents of balance winding and compensation winding. A great deal of experiment has verified the validity of the magnetic potential self-balance and feedback compensation theory sufficiently. Great deals of reliable experiment data are provided
