En outre, le dispositif d'arrêt (4) pour une plage de 10 KA (kiloampères) à 5A (ampères), et le filtre de bruit (21) d'une bande de fréquence intermédiaire allant de 1 000 mégahertz (MHz) à 500 mégahertz (MHz) sont montés, ce par quoi les bruits de la bande de fréquence allant du niveau faible au niveau élevé sont absorbés et l'entrée des ondes de rebondissement de décharge dans un substrat de dispositif électronique (9) connecté à tous les câbles connectés est empêchée.
