ABSTRACT Ice accumulation on transmission lines poses a persistent threat to grid stability, yet precise technical guidance for the dynamic response during ice shedding under wind loads remains insufficient. In response to this issue, this study uses C++ to create a calculation program and obtains aerodynamic coefficients of ice‐covered conductors with

ABSTRACT The synergistic effect of airflow on rainfall behaviour significantly impacts the flashover probability of insulators. This study combines experiments and simulations to investigate the influence of raindrop dynamic behaviour, shed structures and rainfall conditions on flashover characteristics under airflow conditions.

Micro Partial Discharge Characteristics of SF6 Under DC Voltage
ABSTRACT In gas‐insulated high‐voltage direct current (HVDC) devices, micro partial discharges (PD) caused by micro‐protrusions or surface roughness on conductors or enclosures may not cause immediate insulation system failure due to their weak discharge intensity.
