One of the main causes of power transformer failures is due to inter turn short circuit faults. It is a challenging problem to the power engineers to detect these faults at an early stage. If these incipient faults are not detected at their inception, they would develop into more severe faults that may result in damage to the transformer. In this paper a physical model of a multiwinding power transformer...
Recently, the frequency environment of power system has been made more complicated and the quantity of 2nd frequency component in inrush current of power transformer has been decreased because of the improvement of core steel. Traditional approaches will likely be mal operated in the case of magnetizing inrush with low second harmonic component and internal faults with high second harmonic component...
In the present day power system planning and operation, considerable interest is being shown in contingency analysis. Contingency screening and ranking is one of the important components of on-line system security assessment which is done with the help of various computer softwares which employ iterative methods like Newton Raphson and Fast Decouple Load Flow Methods for obtaining the magnitudes of...
