Proceedings: Water treeing and aging
This report presents the record of the workshop Water Treeing and Aging.'' The workshop was held in Phoenix, Arizona on December 9--11, 1990 and was sponsored by the Distribution Program of the Electrical Systems Division of the Electric Power Research Institute (EPRI). Attendance at the workshop was by invitation only. Twenty two attendees from seven countries, from universities, research organizations, electric utilities and polymeric materials suppliers took part in this workshop. The workshop was designed to assess progress in the understanding of water treeing phenomena and polymeric cable insulation aging since the last meeting of a similar forum of experts, which was organized by the Office of Exploratory Research of EPRI in December 1985. The objective of the present workshop was to assess progress and to provide direction for further studies in this field. The discussions covered a wide range of subjects including water tree structure, initiation, growth and breakdown mechanisms, accelerated aging tests for new materials and cables, diagnostic tests, detection of deterioration, tree retardants, field repairs and preventive measures. The workshop discussions were recorded, transcribed, edited and included in this report. The records of the discussions within the breakout groups are also included (Appendices A and B) as they contain information regarding experience from different labs which may be valuable to the reader.
