The operating characteristic of a reactance relay is given by X ≤ 1 Ω, where X is the reactance calculated by the relay. Its operating characteristic in the admittance plane (G-B plane, where G and B denote conductance and susceptance, respectively, expressed in &#herve;) is given by:
A
G2 + (B+0.5)2 ≥ 1/4
B
B ≥ 1
C
(G−1)2 + B2 ≤ 1/2
D
G2 + (B−1)2 ≥ 1/2

Correct : d
