    Hello......
    I am doing the Current Transformer designing for 50Hz input Sine wave.

    But I have struggled to find the Nickel-Iron toroid Magnetic Property(AL Value) Effective parameters(Le cm, Ae squr cm and Ve cube cm) and Dimensional Details of this Toroid for Design calculations.

    With out this information It can't calculate the winding area of the coil.
    pls give me some suggestions to find the Nickel-Iron toroid details.

    Try using the term "permalloy" in your search instead of "nickel iron." It is the trade name for the specific nickel iron alloy used in cores.

    In particular, on the link that Caveman posted, look at the Software link, then Current Transformer.
    They have an application program you can download that will help you design your traditional current transformer, and select the proper toroidal core.
