5 Tips for Managing Your Inspection Program

IR Talk

At The Snell Group, we enjoy meeting new people, talking about IR thermography and all of its various applications, and assisting students when they get back to their respective facilities after class. However, one of the more common things we see is the expectation that having attended a Level I, or even a Level II, IR course empowers the student to administer and manage a full inspection program. It will take more than that.

Why is Insulation Temperature Correction Important

Motor Talk

One of the most widely known test methods applied to electric motors is the resistance to ground (RTG) test. It is commonly referred to as a “megger” test, because one of the meg-ohmmeter manufacturers, Biddle, named their product a “Megger,” and the name stuck. Biddle is now called Megger. Resistance to ground testing can be performed by standalone instruments and is incorporated in types of equipment that provide comprehensive motor testing as part of their suite of tests.
