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.
