Weight of transformer per KVA

  1. Nov 1, 2012 #1
    1. The problem statement, all variables and given/known data

    Cold-roiled steel of high silicon content enables the designer to use higher operating flux densities with lower loss per kg. The higher flux density reduces the weight per kVA.

    Can anyone explain how & why does weight/KVA depends on flux density

    2. Relevant equations


    3. The attempt at a solution

    Higher flux density means you can run the transformer at higher currents. Higher current = higher kVA

    Look up saturation of a transformer core.
