IEC/IEEE 65700-19-03:2025 applies to outdoor and indoor bushings of any voltage used on DC systems, of capacitance graded or gas insulated types for use as components of liquid-filled converter transformers and smoothing reactors, as well as air-to-air DC bushings. It applies to both line commutated converter (LCC), as well as voltage source converter (VSC) technologies. This document does not apply to the following:- cable terminations (potheads);- bushings for instrument transformers;- bushings for test power supplies;- bushings applied with gaseous insulation (other than air at atmospheric pressure) external to the bushing;- bushings for industrial application;- bushings for traction application;- bushings for distribution class transformers.This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:- service experiences as well as established market requirements have been harmonized with existing IEC and IEEE standards, primarily IEC 60137, Insulated bushings for alternating voltages above 1 000 V, and IEEE Std C57.19.00?, IEEE Standard General Requirements and Test Procedures for Outdoor Power Apparatus Bushings;- inclusion of voltage source converter (VSC) technologies.

l'IEC/l?IEEE 65700-19-03:2014 s?applique aux traversées d?extérieur et d?intérieur de toute tension utilisées sur des systèmes à courant continu, à répartition capacitive ou isolées au gaz, pour une utilisation comme composants des transformateurs de conversion remplis d?huile et des bobines de lissage, ainsi qu?aux traversées à courant continu air-à-air. La présente norme fait référence à l?IEC 60137 pour les termes généraux et les conditions générales et définit les termes spéciaux utilisés, les conditions de service, les caractéristiques assignées, les procédures d?essai tout comme les exigences générales dans le domaine mécanique et électrique concernant les traversées pour application en courant continu.
