Understanding Insulation Resistance Testing, September 2023 Webinar by Tom Sandri of Protec Equipment Resources.

In this webinar, we will review insulation and its properties along with basic causes of insulation degradation. We will learn how insulation resistance is measured and how an insulation resistance test set (megohmmeter or hipot) operates. Proper use of an insulation test set along with various types of insulation tests will be reviewed and discussed. Discussions will include potential sources of measurement error, environmental effects on readings and safety associated with the operation and use of a megohmmeter or hipot.
