← TechnologyWhich risk increases when cycling a transformer's load without adequate breaker coordination?
A)Cascading breaker trips occur✓
B)Transformer core saturation increases
C)Eddy current losses stabilize
D)Insulation dielectric strength grows
💡 Explanation
Cascading breaker trips result from incorrect interrupting time settings; the `protective relay coordination` mechanism activates upstream breakers. Because impedance protection is bypassed nearest the fault therefore upstream breakers trip, rather than isolating faults locally.
