Among other things, one or more techniques and/or systems are provided for providing recommendations to address design flaws of power system equipment and/or model design flaws for equipment model types of power system equipment. For example, historical sensor data and/or historical field test data, collected from power system equipment, may be analyzed to identify a design flaw of the power system equipment (e.g., a design flaw of a seal ring). A redesign cost to redesign the power system equipment, a failure impact of a failure from the design flaw, a maintenance repair and/or replacement cost, a manufacture alternative component cost to use an alternative component for manufacturing the power system equipment, and/or other factors may be taken into account to crate and provide a recommendation to address the design flaw.

Power system equipment design flaw identification

Method and system for predicting an oil temperature of a transformer for a desired load and/or predicting a load that a transformer can support for a desired time. A machine learning algorithm is developed using historical data of a transformer. After the algorithm is developed, historical data corresponding to the transformer are input into the algorithm to develop a profile of the transformer describing how the temperature of oil within the transformer is expected to change as a function of a desired load. Using the profile, the of temperature of the transformer is predicted for a desired load. In this way, a prediction is made as to whether and/or for how long a transformer may support a desired load before the oil temperature reaches a specified threshold and/or before the transformer fails due to the load.

Profiling transformer of power system

A computer-implemented system and method for predictive and diagnostic analysis of an electrical transmission, generation and distribution asset health includes a computer with a non-transient computer readable medium able to receive data regarding an asset, its components, component subsystem and parameters related thereto. Instructions stored on the non-transient computer readable medium execute instructions that predictively calculate overall asset health and also calculated the states of subsystems and component parameters, providing a diagnostic of the causes of poor asset health.

System and method for power transmission and distribution asset condition prediction and diagnosis

Among other things, one or more techniques and/or systems are provided for assessing power system equipment of a power system. Historical sensor data and/or historical field test data collected from the power system equipment may be utilized to develop a health profile of the power system equipment. The health profile is indicative of a predicted health (e.g., or probability of failure) of the power system equipment. In one embodiment, the health profile further comprises a health index score which evaluates that health of the power system equipment in terms of the importance of the power system equipment to the power system. Using the health profiles developed for a plurality of power system equipment, a maintenance strategy for at least a portion of the power system may be developed.
