Distribution Automation: Trends, Developments and Retrospectives: 2007-2018
Newton Evans, March 2010, Pages: 30
This summary of key technical and market findings from recently completed Newton-Evans Research studies will assist anyone concerned with the current status and outlook for DA in electric utilities. The 30-page compendium report is loaded with solid information for power distribution equipment manufacturers, utility systems integration firms, telecommunications providers, as well as for utility DA systems planners.
