Abstract
Section titled āAbstractāAbstract As the main device of current measurement in the power system, the current transformer is widely used in the power system measurement, protection monitoring and other important links. But it is difficult for the traditional current transformers to achieve the high-precision current measurement under the conditions of large dynamic range and wide temperature range. With its natural magnetic sensitivity, the diamond Nitrogen Vacancy (NV) color center can measure the magnetic field around the wire and use the inversion algorithm to achieve current measurement, which has obvious advantages over the traditional current measurement principles in terms of sensitivity, stability and working temperature range. In order to realize the current measurement with the diamond NV color center, this paper adopts the current measurement method based on the closed-loop frequency tracking control, and carries out research from two aspects: theoretical method, basic platform design and implementation.
