Description
Bin and co-authors simulate stray metal particles inside high-voltage gas-insulated lines in this 2025 study. Such particles lift off, bounce, and migrate under electric forces, risking insulation failure. Two-dimensional simulations cannot capture their true motion.
The team built a three-dimensional model pairing electric field analysis with particle tracking and random bounce angles. Larger reflection angles widened the particles' radial spread and axial travel. Particles repeatedly bounced between conductor and shell, then drifted toward the convex side of basin insulators. Particles near that convex side climbed along its surface. The authors also mapped how key parameters change particle vigor. The results help predict where particles gather in real equipment.
