Device profiling and predictive failure analysis using discrete wavelet transforms

A power system comprising:

• one or more controllers including one or more processors configured to execute program instructions stored on one or more memory devices, wherein the program instructions are configured to cause the one or more processors of the one or more controllers to:
• receive power signals for one or more monitored devices, wherein a respective power signal includes at least one of a current or a voltage;
• perform discrete wavelet transforms (DWTs) of the power signals to generate DWT coefficients associated with the power signals;
• classify the power signals within two or more classes based on the DWT coefficients, wherein the two or more classes include one or more normal classes associated with one or more acceptable operational conditions and one or more atypical classes associated with one or more atypical operational conditions;
• and
• generate one or more alert signals based on the classified power signals when one or more alert conditions are met.
