Abstract Sulphur hexafluoride (SF6) is a potent greenhouse gas used in high voltage accelerators. As a promising alternative to SF6, the C3F7CN/CO2 gas mixture and its by‐products are of great interest to ensure the safe operation of accelerators t

Electrical trees initiated from defects in solid insulation are one of the main causes of cable insulation failure. Both the initiation and propagation of electrical trees are linked to PD activity in the free volume and interfaces between electrode,

The effect of DC bias on electrical tree growth and partial discharge (PD) characteristics in epoxy resin (Araldite LY ® 5052/Aradur® HY 5052 supplied by Huntsman) is investigated using three waveforms: AC, AC with positive DC bias, and AC with neg

By-products of SF 6 react with water and lead to the formation of highly toxic decomposition products, which cause a reduction in breakdown performance. However, there is limited work carried out on the humidity effect on the DC breakdown characteris

Electrical treeing in solid polymeric insulation is physical evidence of internal damage and ultimately leads to equipment failure. This study considers the effect of frequency on treeing breakdown times in epoxy resin between 50 Hz to 450 Hz. The tr

Electrical tree propagation is a precursor to dielectric failure in high voltage polymeric insulation. Tree growth has been widely studied under AC conditions, but its behavior under DC is not well understood. The aim of this work was to examine the
