Relaying — Power System Protective

: Uses analog electronics for better precision and smaller footprints.

In transmission line protection, the is frequently used to define the "trip zone" on an R-X (Resistance-Reactance) diagram. If the measured impedance falls inside the circle, the relay trips. ✅ Summary

: Faults must be cleared in milliseconds to prevent equipment damage. Power System Protective Relaying

: Microprocessor-based; provides metering, logging, and remote communication. 5. Visualizing Distance Protection

: Calculates the ratio of voltage to current to find fault location. : Uses analog electronics for better precision and
