Which type of fault in a 3-phase power transmission line is the most frequent?

ADouble Line-to-Ground (L-L-G) fault

BSingle Line-to-Ground (L-G) fault

CLine-to-Line (L-L) fault

DSymmetrical Three-Phase fault (L-L-L)

Explanation

Single Line-to-Ground (L-G) faults account for nearly 70% to 80% of all power system short-circuit faults.
