High Current Micro-Ohmmeters

High Current Micro-Ohmmeters

High current micro-ohmmeters are designed for heavy-duty testing of conductors, busbars, and switchgear that carry very large currents. By injecting test currents of 200A or more, these testers provide accurate, repeatable resistance measurements in demanding applications.

Who Uses High Current Testers?

  • Utilities: Substation and transmission equipment testing.
  • Industrial plants: Large motors, generators, and heavy electrical infrastructure.
  • Engineers: Commissioning of high-value electrical assets.

Example Models

  • AEMC 6292: High current tester with professional-grade accuracy.
  • Megger DLRO200 / DLRO600: Widely recognised competitor models.
