Different from EHV transmission lines, the boundary of UHV transmission lines naturally consists of busbar stray capacitance, shunt reactor and/or series capacitor. The frequency characteristics of the UHV line boundaries with different structures ar

Considering travelling wave’s bandwidth which varies from several kilohertz to hundreds of kilohertz, traditional current and voltage transformers cannot transfer whole bandwidth of travelling wave. However, electronic transformers, including Rogow

The liquid state stability of high-entropy alloys (HEAs) are usually taken for granted, because the large configurational entropy for equiatomic multicomponent mixtures of metallic elements can even stabilize disordered solid-solution phases. Here we
