    can any one help me about the CT what i am going to use??


    Current Ratio: 10A / 1.5A
    Secondary voltage:: 1. 60V when Primary current is 10A
    2. 20V when primary current is 1A.
    Frequency: 50Hz


    How to Calculate
    1. Primary/secondary Impedance @ 5A rated primary current for 6watt
    2. Primary/secondary Inducing voltage @ 5A rated primary current for 6watt.

    I don't have information about Turns.

    you can use 1:100 CT and 16 OHM resistor you will 1.6 V when primary has 10A
