Analysis of characteristics for clamping voltage fellowing the application of element for preventing the short circuit of Metal Oxide Varistors for ZnO

ZnO 계열의 금속산화물 바리스터의 단락 방지용 소자 적용에 따른 제한전압 특성 분석

Recently, the natural environment changes drastically, and the frequency of occurrence for lightning has gradually been increased. Such lightning delivers high volume of energy along the power line and communication line to the equipment in use. The high volume of energy arising from the lightning surge develops in fast velocity to destroy the facilities in power source and many other facilities in operation in sequential destruction with vast energy. In this thesis, the analysis on the change of clamping voltage characteristics by the contact resistance and lead inductance by using several case studies through the application of element for preventing the short circuit of Metal Oxide Varistor for ZnO.
