What are unsymmetrical faults?

Unsymmetrical faults are the faults that lead to unequal currents with unequal phase shifts in a three-phase system. The unsymmetrical fault occurs in a system due to the presence of an open circuit or short circuit of transmission or distribution line. It can occur either by natural disturbances or by manual errors. The natural disturbances are heavy wind speed, ice loading on the lines, lightning strikes and other natural disasters. LG, LL, and LLG faults are asymmetrical faults.
