← TechnologyWhich disruptive outcome arises under arcing fault condition in electrical power distribution systems?
A)Transient overvoltages propagate system-wide surge✓
B)Reduced harmonic distortion improves power factor
C)Controlled current limiting via superconducting elements
D)Maintained voltage regulation during power sags
💡 Explanation
When an isolation fault generates arcs, the Electromagnetic Interference (EMI) injects transient overvoltages damaging equipment, because rapid current changes induce voltage spikes via inductive coupling; therefore, propagating disturbances are normal, rather than harmonic improvements stemming under linear load conditions.
