1. A power meter comprising:
- a housing;
a plurality of sensors configured to monitor operation of a motor;
a processor disposed within the housing and configured to receive operational feedback from the plurality of sensors and proactively determine an operational wellness of the motor from the operational feedback;
wherein the processor is further configured to generate baseline data from the operational feedback during known healthy operation of the motor; and
wherein the processor is further configured to perform a fast Fourier Transform (FFT) on the operational feedback to compare a frequency spectrum of the operational feedback to the baseline data to determine the operational wellness of the motor.

11. An overload relay comprising:
-
a relay housing; a power meter disposed within the relay housing and configured to receive data from a motor and perform motor fault protection; a wellness system disposed within the housing and configured to review the data and proactively determine a wellness of the motor to generate condition based maintenance alerts wherein the wellness system is further configured to communicate the condition based maintenance alerts upon determining an undesirable wellness of the motor; and wherein the condition based maintenance alerts are communicated over a communications network to an operator display. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A kit configured to retrofit a relay comprising:
-
a housing having dimensions substantially similar to an overload relay; an interface configured to receive feedback from a plurality of sensors monitoring a motor; a wellness system disposed within the housing and configured to receive the feedback from the interface and determine whether preventative maintenance is required on the motor wherein the wellness system is further configured to compare the feedback to historical data and output preventative maintenance alerts if the feedback is outside a tolerance; and wherein the preventative maintenance alerts include cavitation alerts, motor alignment alerts, and motor rotational unbalance alerts. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
