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.  

Expert recommends

CIBANO 500

CIBANO 500 outputs up to 200 A DC for static contact resistance measurements with very high accuracy with a digital μΩ meter.

Prevent Subsequent Faults
Discover creeping contact resistance increase problems long before these problem areas would lead to an electric fault.
Powerful integrated supply
The integrated power supply can output a highly accurate, digitally generated output signal of up to 2.4kW.
High measurement accuracy
Using four measurement ranges, CIBANO 500 can accurately determine contact resistances with an accuracy of better than 1 µΩ.

Other solutions

CPC 100

The multifunctional CPC 100 can output up to 400 A DC for static contact resistance measurements.

Other solutions

COMPANO 100

The multifunctional COMPANO 100 provides up to 100 A DC to measure static contact resistance.
