Abstract There is evidence that humans can survive a direct lightning strike to the head. Our question is: could water (rain) on the skin contribute to an increase in the survival rate? We measure the influence of rain during high-energy direct light

Direct lightning strikes to the human head can lead to various effects, ranging from burnings to death. The biological and physical mechanisms of a direct lightning strike in the human head are not well understood. The aim of this paper is to design

Due to the increasing use of power electronic converters in electrical grids, high voltage insulation systems are stressed by medium frequency voltages. The breakdown voltage of air decreases with increasing frequency especially for inhomogeneous ele

Similar to a normal wave, a shock wave travels as energy through matter but it causes an abrupt rise of pressure, temperature and density. In this study, the influence of shock waves on wood struct...

The increasing usage of medium-voltage direct-current in upcoming electrical energy grid topologies requests novel solutions for MVDC switching. The interruption of direct-currents is accomplished by enforcing a current zero crossing by adequate mean

A big challenge for future electric grids is the energetic coupling of DC systems. This can be realized by Solid-State-Transformers with an operating medium frequency AC voltage generated by power electronic converters. The DC voltage and the superim

Lightning is a natural phenomenon in the field of high voltage discharges where high voltages and transient currents occur instantaneously. A lightning strike to the body especially to the head represents the most severe case where it is known that h

In the presented work we examine the effect of a high DC field on the dielectric loss tangent (tanδ) and the relative permittivity (e′) of Transformerboard, a cellulosic fibrous insulating material. The dielectric dynamics was studied by applying

There is evidence that humans can survive a direct lightning strike in the head. The formation of a flashover outside of human body might be a reason for the survival. However, the current density distribution inside the human head and the formation
