    Comprehensive analysis of CT experiment

    The main function of the current transformer, as an indispensable measuring tool in the power system, is to convert the primary side of a high current into the secondary side of a low current through the magnetic effect in order to facilitate measurement and use. The core structure of the device consists of a closed core and windings. Its primary side winding has a low number of turns and is directly connected in series with the circuit of the current to be measured. In practice, the secondary side is usually configured with double or multiple windings to meet different measurement requirements.
