AEMC offers Understanding Insulation Resistance Testing
Training Seminars

A regular program of testing insulation resistance is strongly recommended to prevent electrical shocks, assure safety of personnel and to reduce or eliminate down time, yet, insulation testing procedures are often not fully understood. This comprehensive, one day seminar is designed to give you thorough knowledge and understanding of all aspects of insulation resistance testing as well as the use of the equipment required to perform these tests.

Key Topics Covered
  • Motor Theory
  • Spot Testing
  • Timed Tests
  • Polarization Index
  • Temperature Correction of Test Results


    AEMC offers Understanding Ground Resistance Testing
    Training Seminars

    The training seminar consists of two sessions. The first session consists of classroom presentations and discussions on all aspects of soil resistivity and ground resistance testing.

    The second session consists of on-site field tests demonstrating the different methods of ground resistance testing discussed during the first half of the day.

    What You Will Learn
  • When and how to use each test method
  • When and where not to use a particular test method
  • Proper placement of auxiliary rods to conduct each type of test
  • How to calculate the required ground electrode depth based on soil resistivity data
  • How to distinguish ground resistance measurements from loop resistance
  • How to use the Fall-of-Potential method when it is not practical to drive auxiliary rods
