Ductor

Micro-ohm measurement of busbars, joints, and power connections.

Ductor

What is it

Low resistance measurement of joints to confirm high-quality continuity with current injection.

Why is it done

Prevents hot spots, losses, and failures from deficient or oxidized joints.

How is it done

  • High injected current and voltage drop measurement.
  • Compensation of thermo-forces, 4-wire use, and stabilization before recording.
  • Verify repeatability and record mounting conditions.

Expected results

  • mΩ values consistent with design/length/section.
  • Anomalies → cleaning, re-tightening, surface improvement, or replacement.
