Static Contact Resistance of Disconnectors and Joints
Measuring static contact resistance verifies whether the resistance of current carrying contacts, in particular joints, allows the flow of rated current within specified losses. The resistance depends on contact surface properties which are the connection points on micro-scoping level, the contact pressure and the oxidation of the surface.
