Apparatus for measuring current |
| abstract |
A low frequency measurement sensor for measuring a magnetic field generated by a measured current, A high frequency measuring sensor disposed so as to be substantially in parallel with the low frequency measuring sensor so as to measure the magnetic field and generate a magnetic field for canceling the magnetic field applied to the low frequency measuring sensor; A negative feedback circuit for controlling a current flowing through the high frequency measurement sensor based on the magnetic field signal measured by the low frequency measurement sensor, A low pass filter arranged in the negative feedback circuit for adjusting the frequency characteristic of the current controlled by the negative feedback circuit and flowing to the high frequency measurement sensor; And an output unit for outputting a measured value of the measured current based on the current flowing in the high frequency measuring sensor. |
