static balancer

Can some one please explaine to me if possible how a static balancer works? I've seen a couple of these things installed at the end of long LV  distributors but never been able to find how they work as far as I can tell they are just 3 windings connected in star  but I've got no clue how they balance voltage.

  • It is a type of transformer, so designed that if one phase has a higher voltage than the others, that power is "sucked" out of the higher voltage phase and "pushed back into" the lower voltage phases.


    In years gone by, "rotary balancers" were used, a form of induction motor that achieved a similar purpose.

    Rotary balancers were also used on 3 wire DC mains to draw power from the higher voltage side and generate to feed back into the lower voltage side.

    Also used to derive a 3 wire system from a 2 wire DC supply.
