Low-pass filter function ii. Ebooks Electrical engg vol-1 Electriacl engg vol-2 Electrical engg vol-3 Electrical engg vol Power factor will be lowered Transient stability can be improved by a By putting series capacitor b By using dynamic resister c Auto re-closers d All of the above Ans: Vab is reference then angle between Vab and Ib is a deg b deg c deg d deg Ans: Va and Vb are negative sequence component voltages the difference angle between Va and Vb with respect to Va is a b c d Ans: When Alternator excitation increases and machine is operating at lagging power factor then a I increase b I decreases c No effect on current d Apteansco Ans: Harmonics are eliminated by using a Skewing of rotor b Distribution winding c Short pitch winding d All of the above Ans: A dc cumulatively compounded motor delivers rated load torque at rated speed.
Temperature of electrode in Arc furnace is a deg b deg c deg to deg d deg Ans: Find Vab a Zero b aptransci at an angle of 90 deg c 50 at an angle of 90 deg d None Ans: Mho relay is usually employed for the protection of a Short lines only b Medium lines only c Long lines only d Any line Ans: Long lines only 2.
Less fluctuation from no-load to full-load The two watt meters measurement the ratio of two meter readings is — 1-sqrt3: Lag net work Field flux production The phase lead compensation is used to a Increase rise time and decrease overshoot b Decrease both rise time and overshoot c Increase both rise time and overshoot d Decrease rise time and increase overshoot Ans: In bode plot the point which separates ffor lower and upper frequencies is called a Critical point b Cut-off point c d Ans: A CRO screen has ten divisions on the horizontal scale.
