125. The phase comparators in case of static relays and electro-mechanical relays normally are: (a) Sine and cosine comparators respectively (b) Cosine and sine comparators respectively (c) Both are cosine comparators (d) Both are sine comparators. 126. The order of the lightning discharge current is: (a) 10,000 amp (b) 100 amp (c) 1 amp (d) 1 microampere. 127. The magnetising-inrush-current in a transformer is rich in: (a) 3rd harmonics (b) 5th harmonics (c) 7th harmonics (d) 2nd harmonics. 128. For effective use of a counterpoise wire: (a) Its leakage resistance should be greater than the surge impedance (b) Its leakage resistance should be less than the surge impedance (c) Its leakage resistance should be equal to the surge impedance (d) The two resistances may have any relation. 129. The inertia constants of two groups of machines which do not swing together are M1 and M2. The equivalent inertia constant of the system is: (a) M1 + M2 (b) M1 – M2 if M1 > M2 (c)M M M M 1 2 1 + 2 (d) M1-M2
