IEEE Draft Guide for the Selection of Neutral-Grounding Devices for High Voltage Direct Current (HVDC) Converter Transformers
Preview
Summary
New IEEE Standard - Active - Draft.
This guide recommends the applications, selection principles, technical requirements and test requirements for dry-type and liquid immersed neutral-grounding devices used with HVDC converter transformers. This guide applies to converter transformers with a star connected winding on the grid side and a delta connected winding on the valve side.
The purpose of this guide is to summarize the principles of selecting neutral grounding devices for HVDC converter transformers to help address the problem of single-phase short-circuit overcurrents in HVDC substations with directly grounded converter transformers.
