1. A power meter comprising:
- a housing;
a plurality of sensors configured to monitor operation of a motor; and
a processor disposed within the housing and configured to;
receive operational feedback from the plurality of sensors;
identify data in two frequency sidebands of a system frequency in the operational feedback; and
determine an impending mechanical fault of the motor from the identified data before occurrence of the mechanical fault.

9. An overload relay comprising:
-
a relay housing; a power meter disposed within the relay housing and configured to receive a motor current spectrum from a motor and perform motor fault protection; and a wellness system disposed within the housing and configured to; analyze data in two frequency sidebands in the motor current spectrum; and proactively determine a wellness condition of the motor from the analyzation before a fault occurrence to generate condition-based maintenance alerts indicating an imminent fault occurrence. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. 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; and a wellness system disposed within the housing and configured to; receive the feedback from the interface; analyze two frequency sidebands in the feedback; and determine from the analyzation whether preventative maintenance is required on the motor based on a prediction of a fault condition of the motor to prevent the fault condition. - View Dependent Claims (17, 18, 19, 20)
