Peculiarities of nonsustained disruptive discharges at interruption of cable/line charging current
Tóm tắt
It has been found out that NSDD probability increases at cable/line charging current interruption compared with no-load test. This fact has been explained by formation of contact welds at closing of the preliminary charged cable/line. These welds being torn apart at the following contact partition may serve as a source of macroparticles or surface irregularities resulting in increased probability of NSDD.
