| Guide d'application des éléments de protection contre les surtensions – Transformateurs d'isolement à haute fréquence |
Certaines défaillances au niveau des ports de réseau local (LAN) Ethernet ont été attribuées à l'utilisation de dispositifs de protection contre les surtensions (SPD) inappropriés, une coordination de l'isolement insuffisante et un câblage inapproprié, ce qui entraîne des défaillances au niveau des transformateurs ainsi que du câblage, des éléments et des connecteurs associés. La Recommandation K.126 porte sur les paramètres des transformateurs d'isolement et sur leurs incidences sur les performances des équipements en cas de surtensions en mode commun ou en mode différentiel. Pour bien comprendre ce document, il est nécessaire de consulter la Recommandation [UIT-T K.95] dans son intégralité. |
