Contact Resistance Optimization
The challenge
Contact resistance determines how much heat a connection produces. Elevated resistance is often the first sign of degradation and a precursor to failure.
Our approach
Nexums advises on reducing and monitoring contact resistance: contact surface treatment, coatings, contact pressure and measurement strategy. We review measurement results (micro-ohm) and interpret trends.
Standards framework
IEC 62271
Result
Concrete recommendations to reduce contact resistance and a measurement strategy to detect degradation in time.
FAQ
What is contact resistance optimization?
Advice on reducing and monitoring contact resistance in high-voltage connections, including contact-surface preparation, coatings, contact pressure and measurement strategy.
Why is contact resistance such an important indicator?
An increased contact resistance is often the first measurable sign of degradation, well before visible damage occurs.
Which measurements are used for this?
Nexums reviews micro-ohm measurements and interprets trends in them, to detect degradation in time before a connection fails.
