Which risk increases when a long transmission circuit breaker trips under a heavy inductive load?

💡 Explanation

When a lightly loaded transmission line is suddenly opened, the Ferranti effect causes a voltage rise at the receiving end because charging current leads the voltage, leading to overvoltage. Therefore, voltage escalation results, rather than saturation, breakdown or malfunction which involve different electrical phenomena.
