Which consequence results when over-voltages induce flashover inside switchgear circuits?

💡 Explanation

An arc flash occurs because ionization generates a conductive plasma that allows current to flow through the air. Therefore, the switchgear’s compartment rapidly heats due to the arc flash thermal energy, rather than modifying transmission or optimizing power.
