The operating characteristic of a reactance relay is given by $X \le 1 \Omega$, where X is the reactance calculated by the relay. Its operating characteristic in the admittance plane (G-B plane, where G and B denote cond...

Consider the two statements given below, and select the correct option. Statement 1: A directional relay relies on the principle that the CT currents due to fault location on either side of the CT, always differ from eac...
