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.

Abstract: A system includes: an electrical apparatus that includes: a housing that defines an interior space; an active portion in the interior space; and insulation configured to electrically insulate at least part of the active portion. The system also includes a monitoring apparatus configured to: receive measured data from the electrical apparatus; determine a load forecast for the electrical apparatus based on the measured data; determine whether a pre-determined time interval has elapsed; and after the pre-determined time interval has elapsed: estimate an actual amount of life lost for the insulation during the pre-determined time interval that elapsed based on the measured data; estimate a predicted amount of life lost for the insulation during one or more future time intervals based on the load forecast; and estimate a remaining service life for the electrical apparatus based on the actual amount of life lost and the predicted amount of life lost.

CPC classification number: G01R31/62
Abstract: A system includes a monitoring module configured to: receive a first indication related to a three-phase input of a three-phase AC electrical asset; receive a second indication related to a three-phase output of the three-phase AC electrical asset; determine performance metrics for the three-phase AC electrical asset based on the first indication and the second indication; determine error metrics by comparing each determined performance metrics to a pre-determined estimated performance metric; compare each of the error metrics to one of a plurality of pre-determined thresholds, the thresholds being determined when the three-phase AC electrical asset is in a healthy condition; and determine whether a developing fault condition exists in the three-phase AC electrical asset based on the comparison.
