    Hi,.... first post and new to designing current transformer.
    what i would like to do is to try to design the Current Transformer for Power System applications.

    Specification:

    100A:60mA current ratio.

    Pls help me to design the CT with Toroidal core.

    Here is a link to the introduction of iron toroid cores:
    http://newtek.com.au/Introduction.php

    I suggest that you read through it. There is a good bit of material presented.

    Most of the battle in designing such things is just knowing where to find the documentation.

    I will do mmf, Flux density, Secondary emf calculations.
    I could't calculate the Required toroidal area and circumference, H and AL value using this data to choose the Toroid.
