Economic and technical aspects of transformer operation

ABSTRACT

The increasing need for electrical energy is solved by expanding electric power plants, which requires large investments. One of the most expensive plants of this kind is the electric power transformer. The problem of exploitation of existing transformers has always been present. Due to the difficult conditions that our economy, and therefore mining, is facing, this issue has increasing importance. In response to this, the article analyzes the conditions of transformer optimum exploitation.
