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.
CIBANO 500 outputs up to 200 A DC for static contact resistance measurements with very high accuracy with a digital μΩ meter.
The multifunctional CPC 100 can output up to 400 A DC for static contact resistance measurements.
The multifunctional COMPANO 100 provides up to 100 A DC to measure static contact resistance.
