185. The operation of the relay which is most affected due to arc resistance is (a) Mho relay (b) reactance relay (c) Impedance relay (d) all are equally affected . 186. The relay which is most sensitive to power swings (maloperation) is (a) Mho relay (b) reactance relay (c) Impedance relay (d) all are equally affected. 187. A 100/5 A bar primary current transformer supplies an O/C relay set at 25% pick up and it has a burden of 5 VA. The secondary voltage is (a) 1 volt (b) 1.25 volt (c) 2.5 volt (d) 4 volt. 188. A 100 : 5 current transformer has secondary winding and lead resistance of 0.2Ω and the secondary burden is 5 VA. The VA output is (a) 5 VA (b) 10 VA (c) 7.5 VA (d) 2.5 VA. 189. The phase angle error of a current transformer can be reduced by connecting an element across its secondary which is predominantly (a) resistive (b) inductive (c) capacitive (d) independent of the nature of element.
