Abstract
The current sources in power transformers such as leads and windings are also sources of Eddy current losses. Due to these losses some parts of tank wall are subject to serious local overheating. It affects the safety and reliability of these expensive objects and their power delivery. There are various methods for reduction of these eddy current losses. One of them is the internal shielding of transformer tank wall. In this paper the tank eddy current losses reduction, through its shielding is determined.
