The most common type of unsymmetrical
faults in three-phase system is
Single line to ground
Line to line
Double line to ground
Three-phase
Single line to ground
There are mainly three types of faults that happen, which are
●Line (or single line) to ground (L-G)
●Line to line (L-L)
●Double line to ground (LL-G)
Single line to ground (L-G) fault is most common fault and 65-70% of faults are of this type.
Hence, the correct option is (A).
