High voltage device breakdown

Voltages greater than 50 V applied across dry unbroken human skin can cause heart fibrillation if they produce electric currents in body tissues that happen to pass through the chest area. The voltage at which there is the danger of electrocution depends on the electrical conductivity of dry human skin. Living human tissue can be protected from damage by the insulating characteristics … WebP Song ， Z Meng ， X Li ， M Zhu ， S Fang. 摘要：. The ablation of high voltage cable buffer layer has puzzled the field of high voltage cable for nearly 20 years. It has been studied that the development process of this kind of fault is that the buffer layer of high-voltage cable develops from whiteness, ablation to cable breakdown.
