← ScienceWhich risk increases significantly when a long, HVDC power transmission line experiences substantial corona discharge?
A)Electromagnetic interference with nearby circuits✓
B)Increased cable sag from thermal expansion
C)Mechanical resonance in support structures
D)Reduced power factor at the receiving end
💡 Explanation
Electromagnetic interference will increase because corona discharge generates broadband electromagnetic noise via ionization processes within intense electric fields; therefore, nearby circuits are disrupted rather than cable sag, which is affected by temperature, mechanical resonance relates to wind, and power factor is an AC phenomenon.
