Abstract
On the basis of extensive corona detection experience on full reel testing of cables it is proposed that, in addition to corona level, a characteristic designated as "corona factor" be determined on each reel length of high-voltage cable with extruded conductor and insulation shields. The corona factor establishes the relationship between discharges in the cable and voltage stress over a stress range up to several times the operating level. In addition, it is proposed that full reel power factor measurements be made to provide a check on the resistivity of the extruded shields. The use of a novel continuous corona discharge detector in the laboratory to locate defects in the cable core, with insulation semiconducting shield in place, is described.Keywords
