APPARATUS AND METHOD FOR ELECTRICAL MEASUREMENTS ON CONDUCTORS |
摘要 |
A method for measuring at least one characteristic parameter of an alternati ng current in a conductor, the method comprising the steps of measuring the magnetic field around the conductor at a point along the conductor; deriving an analogue voltage signal representative of the measured magnetic field; amplifying the analogue voltage signal; converting the amplified voltage signal into a digital voltage signal; measuring the digital voltage signal and, when the amplitude of digital voltage signal reaches a predetermined value, adjusting a gain setting of the amplification; and generating an outp ut signal representative of the parameter of the alternating current based on t he amplified voltage signal and the gain setting.
