← TechnologyWhich outcome occurs when excessively high inrush current exceeds circuit breaker capacity?
A)Breaker trips, power loss occurs.✓
B)Transformer operates at reduced efficiency
C)Increased harmonic distortion appears.
D)Core saturation induces greater losses.
💡 Explanation
Breaker trips occur because the overcurrent leads to exceeding the instantaneous trip (magnetic trip) mechanism within the breaker, designed to quickly interrupt the circuit. Therefore, power is lost because the circuit opens, rather than the transformer changing efficiency under this failure event.
