🔍 Key Concepts

• Relationship between current setting, instantaneous setting, and time delay / inverse‑time in an electronic overload relay • How a potentiometer working with a capacitor (C2) affects time delay in a protection circuit • Reading the labels on the schematic: Overload Current Setting Pot (R2), Inst. Current Setting Pot, and Time Delay Setting Pot (R6)

💭 Think About

• Look at which components are already identified for overload current and instantaneous current; what functions do R2 and the "Inst. Current Setting Pot" section already serve? • Follow the circuit path from the CT input through to the detector and curve shaping circuits: where does R6 sit, and what other component (like C2) shares that node? • Ask yourself: when a pot is placed in series/parallel with a capacitor leading into shaping/detector circuits, is it more likely controlling how fast the relay reacts, or how much current causes it to react?

✅ Before You Answer

• Verify which labeled component in the drawing already handles the overload current trip setting (pickup level). • Verify which labeled section is called Inst. Current Setting Pot. and note that this corresponds to an instantaneous element. • Check how adjusting R6 would change the RC time constant with C2, and how that relates to an inverse-time / time-delay characteristic, not to protecting the preamp from overcurrent.
