Conductor Theory for Electrical Testing

Conductor Theory
  • CEU Assignment0.6
  • Course Number7.0.0
  • DeveloperNational Training Center

Course Description

Introduces the new technician to and provides essential knowledge for the experienced technician on the theory and sciences associated with Conductors. This training covers: the relationship of conductor resistance and heating, application of DC resistance measurements, AC impedance measurements, and electrical testing of windings and connections using various resistance test methods including a DLRO. Additionally this training covers connection hardware and torque methods. This is a full day, 8 hour classroom course.

Prerequisites: None
Course Duration: 1 day at 8 hours
