Abstract: In one aspect, an electrical apparatus includes: a housing that defines an interior space configured to hold a fluid; and a control system. The control system is configured to: determine a plurality of fault indicators based on a temperature error, where the temperature error is based on a difference between a measured temperature of the fluid and an estimated temperature of the fluid; analyze the fault indicators by comparing each fault indicator to an associated fault specification; and if one or more of the plurality of fault indicators does not meet the associated fault specification: determine whether a fluid leakage condition exists in the electrical apparatus based on the analysis.

Abstract: An electrical apparatus includes: a housing that defines an interior space configured to hold a fluid; and a control system configured to: obtain a measured temperature value of the fluid from a sensor; build a dataset of fault indicator values, where each fault indicator is a numerical value based on a temperature error, the temperature error is based on a difference between the measured temperature value of the fluid and an estimated temperature value of the fluid; generate one or more features from the dataset; apply a classifier to the one or more features to determine a fluid leak output; and determine whether a fluid leak condition exists in the electrical apparatus based on the fluid leak output.
