13 common causes of motor failure

[@bobcocampo]

How can ground fault monitoring predict possible failure of motors?

[@ElecEngineer]

You can use a carbon brush probe attachment, to measure.

@@ElecEngineer Any technical research on ground fault monitoring meter and correlation with motor failure?

How is voltage affecting the efficiency of motors?

[@ElecEngineer]

Transient voltage, under voltage or overvoltage?

[@bobcocampo]

@@ElecEngineer Both. Utility may use under voltage to increase electricity bill

[@ElecEngineer]

​@@bobcocampothe bill is paid for the kw not the voltage neither the ampere, so the bill won't be affected by reducing the voltage, the under voltage has effects on the electrical equipment & cables but not the bill.
