Abstract

In the electrical equipments, there are lots of phenomena such as loosening of connectin parts, So, heat generation and oxidation growth is considered to have a possibility to cause fire. In this Paper, we were carried out to study the oxidation growth and voltage waveform of connecting parts. In case of copper and copper connection, the growing of Cu2O elongated more than the other copper alloys. According to oxidation growth, the voltage waveform is distorted. And the contact voltage and the power dissipation increased rapidly.
