Which risk increases when reclosing a circuit breaker onto a faulted three-phase power distribution line?

A)Transient voltage amplification occurs
B)Arc flash intensity increases
C)Relay miscoordination chance rises
D)Insulation degradation accelerates sharply

💡 Explanation

Arc flash intensity increases because reclosing feeds fault current into an established arc; the increased energy release drives escalation, therefore higher risk of equipment damage and injury, rather than gradual insulation wear or voltage amplification.
