Selecting the wrong surge tester is a costlier mistake than most engineers anticipate. Under-test a winding and latent insulation faults slip through quality control — returning as catastrophic field failures. [...]
Why Voltage Terminology Causes Confusion When technicians first encounter a digital surge tester, one of the most common sources of confusion is the distinction between “surge voltage” and “test voltage” [...]
The Hidden Enemy: Turn-to-Turn Insulation Faults The most dangerous winding faults are the ones you cannot see coming. A motor can pass a standard Megger insulation resistance test in the [...]
