Real-time dynamic loading and thermal diagnostic of power transformers.

A comprehensive approach to dynamic loading of power transformers is presented. It is based on the Annex G equations in the latest IEEE Loading Guide. The IEEE work is enhanced through a continuous update of rated temperatures. The algorithm was evaluated with nine transformer-months of real-time fi...
