Correct answer: A. Direct stroke on line conductor

  • A. Direct stroke on line conductor
  • B. Indirect stroke on conductor
  • C. Direct stroke on tower top
  • D. Direct stroke on ground wire

Explanation

A direct stroke to a line conductor injects the lightning current directly into the electrical circuit, producing severe overvoltages and insulation stress. Indirect strokes and strokes to the tower or ground wire are generally better diverted to earth by the protection system.
