Unsymmetrical fault in power system

Unsymmetrical faults are normal faults that occur when the three phase lines become unbalanced123. Such faults involve only one or two phases, and they do not have equal phase displacement with each other1. Unsymmetrical faults can occur between line-to-ground or between lines23. They can be series faults between phases or between phase-to-ground, or shunt faults that are unbalanced in the line impedances2. Unsymmetrical faults make the system unbalanced3. [pdf]
