A recent measurement shows this motor operating at greater than 100% efficiency; however, electric motors do not operate at efficiencies greater than unity.

Suggested actions

  • Check recent measurements: Is the data mapped to the correct field? Are the units correct? Is the decimal in the correct spot?
  • Check sensors: Are the values you’re receiving in SCADA or reading manually correct?
  • Check system operations: Is this motor paired to a pump? Is the reservoir lower than the source? Is this pump siphoning? If so, then this motor may validly display an efficiency greater than 100% in this application—not because the motor itself operates above 100%, but because the pump application as a system does.
