← TechnologyWhich risk increases when rapid over-voltage occurs within industrial 480V circuit-breaker panels?
A)Arc flash incident severity✓
B)Transformer core saturation levels
C)Capacitor bank service life
D)Conductor insulation dielectric strength
💡 Explanation
Arc flash intensity escalates because ionization increases the conductivity of air via the Townsend avalanche, therefore worsening short-circuit conditions rather than affecting transformer core or conductor properties, where other mechanisms matter.
