← TechnologyWhich action during live line maintenance leads to capacitive discharge via personal grounding?
A)Inductive proximity from nearby phases
B)Electrostatic coupling from energized conductors✓
C)Corona discharge from sharp edges
D)Ferroresonance with transformer windings
💡 Explanation
Electrostatic coupling causes capacitive discharge when a worker grounds themselves without first discharging the isolated conductor, because the *capacitive divider* mechanism quickly equalizes potential. Therefore static coupling creates high transient current, rather than inductive influencing a slower rise.
