Which risk increases when a transformer's dielectric barrier fails?

💡 Explanation

Failure of the barrier causes dielectric breakdown because the electric field exceeds the barrier's strength, therefore widespread arcing and transformer failure occurs, rather than simple heating through hysteresis or eddy currents – these alternatives do not require barrier failure.
