GEOLOGY

Detailed explanation-1: -LG, LL, and LLG are unsymmetrical fault while LLL and LLLG are the symmetrical faults.

Detailed explanation-2: -There are only four possible failures that can take place in an electrical system. These are the open circuit, high resistance, short-to-ground and short-to-power.

Detailed explanation-3: -Unsymmetrical Faults There are mainly three types namely line to ground (L-G), line to line (L-L), and double line to ground (LL-G) faults. The line to ground fault (L-G) is the most common fault and 65-70 percent of faults are of this type.

Detailed explanation-4: -Single line to Ground fault (LG fault) Line to Line fault (LL fault) Double line to Ground fault (LLG fault)
