  • Current Transformers—and Vacuum Cleaners |

    2 mins readI use one to turn on a vacuum cleaner. The usual concept of a transformer consists of two magnetically coupled coils—primary and secondary—with a turns ratio of 1:N. An ac signal voltage V on the primary produces a secondary signal voltage N×V. When a transformer is used as a current transformer, we pass an ac current through the primary.
