Correlation between Load Current Mode and Electrical Contact Resistance of a Closed Pair of Contacts

摘要：

　　The electrical contact resistance of closed contact pair is dependent on contact material physical characteristics, contact type (sphere-flat or flat-flat),contact surface status (clean or contaminated), but also contact current and mechanical load during measuring.The relationships between contact resistance and load current and load force with the use of DC mode and non-constant current mode measurement method are compared in this paper.The variations in thermoelectric voltage of contact pairs as a function of time with constant force load are presented.
