Zusammenfassung: | The invention relates to the technical field of current transformers, in particular to a digital current transformer adopting a low-permeability magnetic powder core. The device comprises a current coil, the current coil adopts a low-permeability magnetic powder core as a magnetic core, the current coil is connected with a low-range channel circuit and an elevation channel circuit, the low-range channel circuit and the elevation channel circuit are connected with a secondary winding of the current coil in parallel, the low-range channel circuit is used for collecting a small-current range, and the elevation channel circuit is used for collecting a small-current range. The elevation channel circuit is used for collecting a large current range. The low-permeability magnetic powder core adopted by the invention has the advantages of good high-frequency characteristic, good direct-current component saturation resistance, soft saturation characteristic and the like, the production cost is relatively low, the curre |
