Possible faults may occur on a transmission line are
1. 3-phase fault
2. L-L-G fault
3. L-L fault
4. L-G fault
The decreasing order of severity of the faults from the stability point of view is:
  • a)
    1-2-3-4
  • b)
    1-4-3-2
  • c)
    1-3-2-4
  • d)
    1-3-4-2
Correct answer is option 'A'. Can you explain this answer?

Possible faults may occur on a transmission line are1. 3-phase fault2....
The different type of faults in power systems are:
  • Single line to ground fault (LG)
  • Line to line fault (LL)
  • Double line to ground fault (LLG)
  • Three-phase faults (LLL or LLLG)
Frequency of occurrence:
  • Among the given faults, LG or line to ground fault is most common and occurs frequently.
  • The order of frequency of occurrence is given below.
LG > LL > LLG > LLL
Severity of faults:
  • Among the given faults, LLLG or 3 phase faults are most severe. LG or line to ground fault is least severe.
  • Line to line fault is more severe than line to ground fault while double line to ground fault is one level severe than LL.
  • The order of frequency of occurrence is given below.
LLL > LLG > LL > LG
