Abstract: A launching tube for use with a liquid filled tank can be sized to accommodate a submersible vehicle for dispensing into the liquid tank. The tank can be an electrical transformer or any other liquid containing tank such as but not limited to a chemical tank. The launching tube can include a valve for insertion into a launching chamber, and a tank side valve for launching of the submersible into the tank. In one form the launching tube includes an antenna for communication with the submersible and/or a base station. The launching tube can also include a sensor such as a camera, as well as an agitator. The agitator can be used to facilitate bubble removal from the inside of the launching tube.

Abstract: A method of estimating future aging of a transformer includes generating probabilistic models of factors that affect effective aging of the transformer, generating probabilistic profiles of the factors that affect effective aging of the transformer based on the probabilistic models, generating expected hot spot profiles from the probabilistic profiles, simulating a plurality of aging scenarios of the transformer based on the expected hot spot profiles and ambient temperature profiles, and estimating future aging of the transformer from the plurality of aging scenarios.
