SUMMARY
Non-equilibrium systems are defined as systems that are not in a state of equilibrium, where forces or thermal conditions are unbalanced. For instance, a mechanical non-equilibrium system occurs when the sum of forces does not equal zero, while a thermal non-equilibrium system is characterized by temperature differences. In semiconductor physics, a device is considered out of equilibrium when there is a splitting of the quasi-Fermi levels. Understanding these distinctions is crucial for analyzing various physical and engineering problems.

A system that is not in equilibrium. 
It depends on the problem your dealing with, but can usually be figured out by the context. For example, a system not in mechanical equilibrium means that the sum of the forces does not equal zero. A system outside of thermal equilibrium means that there are temperature differences throughout. A semiconductor device is said to be out of equilibrium when there is a splitting of the quasi-Fermi levels. etc.
