Which risk increases when a synchronous reluctance motor trips its dedicated circuit breaker?

A)Elevated supply network voltage instability
B)Increased grid frequency synchronization events
C)Potential consequential three-phase power imbalance
D)Transformer core saturation from magnetizing surges

💡 Explanation

A three-phase power imbalance is more likely because the motor's reactive power demand ceases abruptly upon the `breaker tripping`, which can cause phase voltage asymmetries. Therefore imbalance increases, rather than causing immediate large-scale grid instability directly, given protections and network redundancy.
