Abstract :
A new type of direct current sensor is developed which includes two parts: magnetic potential self-balance circuit and feedback compensation circuit. The characteristics of the device are: simple construction, good stability and reliability, and high precision (the error less than 0.1% in range of 40%~100% rated current)
