System and method for condition based maintenance for electrical equipment

A method comprising:

• receiving, by a system, test data representing an attribute of a tested electrical device, wherein the received test data is associated with a test date on which the test data was obtained from the tested electrical device;
• determining a difference between the received test data and stored test data corresponding to the attribute from at least one previous test conducted on a preceding test date;
• determining whether the difference exceeds a defined threshold;
• and
• assigning a new designation within the system to the tested electrical device if the difference exceeds the defined threshold, wherein the new designation is used by the system to differentiate between a first state of the tested electrical device before obtaining the received test data and a second state of the tested electrical device after obtaining the received test data;
• processing the received test data using one of a sparse data process and an autoregressive process to obtain a first derivative and a second derivative representing the received test data;
• determining a probable future position of the attribute relative to control information representing information corresponding to the attribute for a plurality of electrical devices, wherein the determining is based on the first derivative and the second derivative;
• and
• outputting at least a representation of the probable future position.

A system comprising:

• a database having client information and control information stored therein, wherein the client information includes a separate client class containing data corresponding to each of a plurality of clients and the control information includes at least one control class containing data corresponding to a combination of the plurality of clients;
• a computing device having a processor coupled to the database, a memory coupled to the processor, and a plurality of instructions stored in the memory and executable by the processor, the instructions including instructions for:
• receiving, by the system, test data representing an attribute of a tested electrical device;
• classifying the received test data as belonging to a first client of the plurality of clients, adding the received data to the first client's client class, and adding the received test data to the control class;
• processing the received test data using one of a sparse data process and an autoregressive process to obtain a first derivative and a second derivative representing the received test data;
• determining a position of the attribute relative to control information representing information corresponding to the attribute for a plurality of electrical devices, wherein the determining is based on the first derivative and the second derivative;
• and
• outputting at least a representation of a future value of the position.
