Radiography potential for oil-filled pipe-type cable inspections

OSTI ID:7105651
A program for evaluating the position of cable components in oil-filled pipe-type cables is in place at a large hydroelectric installation. The position of cable components within potheads, trifurcators, and splices is being monitored on an annual basis. Downhill migration of the cable has been observed. A sophisticated radiographic technique was developed to accurately measure the extent of migration, with the intent of preventing costly cable failures. High definition radiographs, taken at full cable loading (400 MW), have permitted accurate position evaluations, which are used to establish repair priorities and maintenance schedules. In addition, potential irradiation damage to cable materials has been evaluated.
