🔍 Key Concepts

• Meaning of inverse time in protection relays (how trip time changes with current level) • Difference between instantaneous overcurrent protection and inverse-time overcurrent protection • Which devices in the diagram already protect against short-circuits and unbalanced stator currents

💭 Think About

• Look at the label block that includes OCIT, OC (inst), and NPS together and think about why three different protections are grouped there • Ask yourself: if a relay is called inverse time overcurrent, should it react faster or slower when the current is higher? How does that relate to long-term overloads versus sudden faults? • Compare what type of fault each choice describes against what the other relays in the diagram (DIFF, NPS, OC inst) already cover, so you don’t assign the same job to two different relays

✅ Before You Answer

• Confirm that inverse time means the trip time decreases as current increases • Identify which relay in the diagram would most logically deal with extremely high short-circuit current (hint: look at OC (inst)) • Identify which function in the list of choices would match protection against unbalanced stator currents, and see which relay label in the diagram already suggests that role (NPS = Negative Phase Sequence)
