    Iran Core Transformator No Load Current (Core material)

    Hello friends

    I have two types of iron to make the iron core Transformator
    In the same number of rounds

    220v to 12V

    Type A No Load current = 130ma

    Type B No Load Current = 100ma

    What can we conclude empirically?
    Is Type B Better?

    Thanks

    May be better. For completeness, we would measure current phase angle. Current can be lower due to higher permeability or lower losses.

    type B may be thinner lams or toroidal...? = lower losses

    or more turns on pri wdg ...

    Re: Iran Core Transformator No Load Current (Core material)

    You need to measure real core loss, with a wattmeter that measures true power= V*I*cos(alpha).

    The core material with the lowest losses, all other things kept identical, is the best.

    When I say all other things should be identical, I mean IDENTICAL. Including the applied voltage.
