EMAX identifies misfiring transistor in a VDF

Overview:

Read this case study to learn what the PdMA EMAX tester identified as the problem, how it was repaired and the potential cost avoided.

A utility had four identical VFD driven motors, but one motor exhibited vibration at high frequencies. Was this insulation degradation as the manufacturer suggested or something else? MCE standard and PI tests ruled out insulation problems. Read this case study to learn what the PdMA EMAX tester identified as the problem, how it was repaired and the potential cost avoided.
