A transformer protection relay does not replace upstream devices. It defines responsibility. By clearly assigning fault ...

Abstract: This paper presents a comparative study of transformer inrush current and fault current. As the transformer is one of the key component in power system network so stability, security and ...

Abstract: In power systems, high-impedance transformers are now widely used because they effectively limit short-circuit current. Among them, the built-in high-voltage-winding type— being less ...

Flu is surging across most of the U.S. But, amid an early, harsh season, there is a glimmer of promising news: The flu shot may be more effective than experts predicted. Early evidence shows that this ...
