← TechnologyWhich action results from exceeding Inverse Definite Minimum Time relay setting in a power management system node?
A)Circuit breaker trips faster✓
B)Transformer core saturation increases
C)Voltage regulation becomes unstable
D)System frequency deviation decreases
💡 Explanation
The power system uses the Inverse Definite Minimum Time (IDMT) relay. When an overcurrent condition persists beyond a defined time, the relay trips a circuit breaker because the *time-current characteristic* rapidly decreases trip time; therefore, faster breaker tripping results, rather than instability or frequency deviations at a source node.
