APPARATUS FOR DETECTING AC COMPONENTS IN A DC CIRCUIT AND USE OF THE APPARATUS |
摘要 |
A device for detecting alternating-current components iAC of an electric current iACDC flowing in a direct-current circuit includes an inductor arranged in the direct-current circuit, and an AC path arranged electrically in parallel with the inductor, wherein the AC path comprises a series circuit made up of a capacitor and a primary winding of a transformer. The device further includes a voltage measuring device, wherein a secondary winding of the transformer is connected to the voltage measuring device via a low-pass filter circuit. |
