Charge Accumulation Characteristics of SF6-Epoxy Interface Under Negative Repetitive Nanosecond Pulses
Repetitve nanosecond impulses in gas-insulated metal-enclosed switchgear (GIS) are likely to trigger inside flashover.Interface charges on the spacer in GIS are considered one of the main factors damaging insulation performance and may be induced by overvoltage.For good understanding of insulation failures, accumulation characteristics of charges b
