Power System Load Balance: Explained

[JohnSimpson]

In the context of power systems, what does it mean for a load to be unbalanced? Or for that matter, balanced?

hi,

if we are talking about 3-phase transformer

unbalanced system or load means that the amount of the load you connect for each phase is not equal and that will cause the nutral to be not zero.

it also happens in the distribution transformer.
