Why Dc Component Present In Fault Current at Oscar Nimmo blog

Why Dc Component Present In Fault Current. This paper presents a study on the dc offset in the fault current in a mv distribution network with local synchronous and/or induction machines. This study demonstrates the accurate signal model to be used for fault generated instantaneous current signals containing decaying dc offset by considering initial loading. The initial value of the dc component is dependant on the exact time. A fault is suddenly applied to the system and the sine wave suddenly becomes asymmetrical (the positive and negative peaks. An initial capacitive discharge transient current and a subsequent static fault current. At the initiation of a fault, the current in any system inductance cannot instantly change from its value at fault inception to that of its steady state fault. The unbalanced current flows in the circuit during the earth fault is known as the zero sequence current or the dc component of the fault current.the three vector lines represent the zero sequence current. A dc fault current typically comprises two parts: Addition of the dc component to the symmetrical short circuit current gives the asymmetrical fault current.
