Abstract
Monitoring the condition of an electrical apparatus based on an estimated temperature of a conductor in the electrical apparatus, including receiving a measured temperature value from a first thermal sensor disposed in the electrical apparatus and configured to sense temperature at a location separated from the conductor by an insulator, generating an estimated conductor temperature value based on applying a non-linear model to the measured temperature value, and monitoring the condition of the electrical apparatus based on the estimated conductor temperature. The non-linear model may include a Hammerstein Wiener model.
