Abstract: An electrical apparatus includes: a housing that defines an interior space; an active portion in the interior space, the active portion including one or more electrically conductive coils; a fluid in the interior; and a control system configured to: determine a difference between a measured temperature of the fluid and an estimated temperature of the fluid; and determine whether a performance condition exists based on the difference.

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.
