Working Groups

Recent Updates

If you are interested in participating in one or more of the working groups, please send your name, email address, and a current CV to John McDonald at johndougmcd@gmail.com. The working groups will be staffed quickly so your prompt response will be necessary.

Working group members should have their company support and be current CIGRÉ members with their current dues paid.

The final choice of members is the responsibility of CIGRE technical officers and the study committee chair and working group convener. The U.S. National Committee can only make a recommendation.
