Reactive inductance
WebApr 11, 2024 · Les bobines d’inductance sont utilisées à la terminaison d’une ligne de transport d’énergie pour neutraliser la puissance réactive produite par la capacitance de la ligne. Plutôt que de faire passer la tension d’un niveau à l’autre, comme le font les PTP, les bobines d’inductance réduisent la chute de tension en absorbant la ... WebFeb 13, 2024 · Reactive power, denoted with Q, is transferred when the current and voltage are 90 degrees out of phase. In such a case, the net energy transferred in the AC circuit equals zero, and we do not loose any real power. Reactive power never appears in DC circuits. In AC circuits, it's linked to the reactance produced by inductors and capacitors.
