What are Symmetrical & Unsymmetrical Faults?

WebbSymmetrical Faults These are very severe faults and occur infrequently in the power systems. These are also called balanced faults and are of two types namely line to line to ground (L-L-L-G) and line to line (L-L-L). Symmetrical faults Only 2-5 percent of system faults are symmetrical faults. Webb27 sep. 2024 · Symmetrical faults do not give rise to zero sequence or negative sequence components because they are perfectly balanced, symmetrical faults only have positive sequence values.
