When does DeltaG=0

Why does DeltaG=0 when there is a phase change?

only when the system is at equilibrium.

For a phase change, that means that the reaction is taking place under conditions at which the two phases are at equilibrium.
For example, when liquid water freezes, the ice must be formed at and 1 bar pressure, where the reactants and products, in this case, liquid water and ice, are in equilibrium.
