This paper presents a traveling-wave-based fault-location algorithm for hybrid multiterminal
transmission systems that consist of one onshore overhead lines and multiple offshore …

Abstract Properties of positive and negative leaders develo** in air gaps ranging from 4 to
10 m that were subjected to 100/7,500‐μs voltage impulses were examined using a two …

The leader propagation is one of the most important stages in long air gap discharge. The
mechanism behind leader re-illumination remains unclear. In high humidity conditions (20.0 …

The numerical modeling of electrical discharges occurring in atmospheric air has been in
continuous development during the past decades in different fields, such as high-voltage …

Phase‐to‐phase air gap is a type of external insulation in power transmission and
transformation projects. The dielectric strength of phase‐to‐phase air gaps affects the safety …

Equipotential live-line work (EPLW) is an indispensable technology to ensure the power
supply. Due to the huge risks of the strong electric field, the distance of the EPLW air gap …

The final jump is an essential process of long air gap discharge. This paper will focus on the
experimental study on the characteristics of the final jump stage under positive switching …

The modular multilevel converter (MMC) technology is being utilized in ultrahigh voltage
direct current (UHVDC) transmission for much larger power transmission and a series of …

Positive leader steps are currently not well understood. Many recent findings challenge the
previous understanding of the positive leader steps occurring in continuous leader …

The front time of switching impulses has a significant influence on long air gap discharge
performance, but most testing experiments have been conducted using standard impulses …
