Protocol for reporting the Operational Performance of HVDC Systems - TB 956

Tue, Nov 3, 2026 2:30 PM - 4:00 PM CET

This webinar will explain the protocol for reporting operational performance of HVDC systems, as per Technical Brochure 956. CIGRE B4 Advisory Group AG-04 (initially SC14 WG-04) was formed in the 1960’s specifically to assemble and publish data on the reliability and operational experience of HVDC systems in service around the world.

The Advisory Group developed definitions for the reliability terms and parameters and prepared a protocol for collecting and compiling the data (recently updated version is Technical Brochure 956). The first data were collected in 1968, covering 4 HVDC systems utilizing mercury arc valves. The HVDC survey data is published every 2 years at the CIGRE Session in a paper titled, “Survey of the Reliability of HVDC Systems throughout World“.

This webinar will be presented by Josh Burroughs and registration is free for all, CIGRE members and non-members.

Technical Brochures, can be freely downloaded by CIGRE members. If you are not a CIGRE member, join now.
