EC&M Tech Talk - The Why, What, and How of High Potential (HiPot) Testing

In this EC&M Tech Talk, Randy Barnett, NFPA Certified Electrical Safety Compliance Professional, demonstrates how to safely use a high potential test set (HiPot) as he conducts an AC Dielecrtic Withstand Test.
Here is the Tech Talk in a nutshell:
• After a brief introduction into the terminology of the topic, Randy demonstrates the how-to side of safety when it comes to performing any test at greater than the insulation rating of the equipment.
• The difference between the dc Insulation Resistance Test and the High Potential Test are presented, then a dc insulation resistance test is performed.
• Important References are presented.
• The AC Dielectric Withstand Test basics are explained.
• A dc Insulation Resistance is performed on a 460 vac motor.
• An AC Dielectric Withstand Voltage Test is performed on the AC motor. Closeups of the HiPot screen shows how to setup the test set.
• Various HiPot applications bring the Tech Talk to a close.
If you have a need to learn what high potential testing is all about, or just want to learn more about testing methods, viewing this EC&M Tech Talk can be of great benefit.
