← ScienceWhich outcome results when standing waves form on HVDC transmission lines?
A)Increased dielectric stress on insulators✓
B)Reduced transmission-line skin effect losses
C)Enhanced power factor correction locally
D)Minimized corona discharge and audible noise
💡 Explanation
Standing waves cause voltage antinodes, resulting in heightened voltage magnitudes. This increases dielectric stress because the higher voltages intensify the electric field, therefore increased risk of insulator failure, rather than lower stress under stable voltage.
