Which risk most immediately intensifies when SF6 circuit breaker density decreases?

💡 Explanation

Lower SF6 density reduces the dielectric strength; consequently, arc quenching ability diminishes because insulation breakdown resistance declines; therefore higher density is utilized to lessen arcing, rather than impact transformer saturation.
