High Voltage, EarlyView.ABSTRACT For designing aeronautical components, the creepage distance is usually estimated by considering the pollution level and the dielectric material group as defined by the standard IEC 60664‐1. The material group is expressed by the comparative tracking index (CTI) performed at atmospheric pressure following the standard IEC 60112.

High Voltage, EarlyView.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
