Current practices on power transformer monitoring and controls for smart grid applications

Power Transformers are critical components of modern electrical transmission and distribution systems. Even though they have been developed more than a hundred years ago, voltage and power ratings continue to increase making them even more critical technically and economically. This paper presents current practices on utilization of modern measurement and diagnostic systems as well as controls to support ever increasing needs of system reliability and economical utilization of various sources of generation, including renewable and distributed along with more traditional base load generation sources.
