Contact Resistance Tester

Contact Resistance Testers & Meters for Sale

The contact resistance test (commonly known as the Ductor test) measures the resistance of electrical connections such as joints, terminations, connectors, etc. These can be connections between any two conductors, for instance busbar sections or cable connections. The test measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are made properly, and can detect the following problems:

  • Loose connections
  • Adequate tension on bolted joints
  • Eroded contact surfaces
  • Contaminated or corroded contacts

This is particularly important for contacts that carry large amounts of current (e.g. switchgear busbars) as higher contact resistance leads to higher losses and lower current carrying capacity.
