Stray Voltage Analysis
EnVibe has added another tool to ensure your Equipment Reliability: Stray Voltage Analysis.
If you’ve ever heard the high-pitch whining sound from your VFD and/or large motors (over 100 horsepower)motor, it’s an indication that EDM (Electric Discharge Machining) is in action.
Do your bearings ever look like this?
These are common examples of EDM, a clear indication that your stray voltage system you have in place is not working.
Some of this material degradation caused by EDM is microscopic, like frosting. Bearings that should last 6–10 years can be reduced to a 2–6 month life.
With Stray Voltage Analysis, EnVibe can determine whether your motors are at risk and implement corrective procedures.
