what are asymmetrical faults?briefly describe how these fault levels are calculated.
In the field of Electrical Engineering an Asymmetrical Fault is a condition in which the load in a 3 phase power supply becomes unequal on all the three phases.
Asymmetrical fault thus gives rise to a situation that contradicts the properties of a three phase power supply that is the load should be equal on all the phases.
Because of this contradiction the asymmetrical faults are difficult to analyze practically, so the study of these asymmetrical faults is done through a proper study of the symmetrical faults.
