A distribution feeder of 1 km length having resistance, but negligible reactance, is fed from both the ends by 400 V, 50 Hz balanced sources. Both voltage sources S1 and S2 are in phase. The feeder supplies concentrated loads of unity power factor as shown in the figure. The contributions of S1 and S2 in 100 A current supplied at location P respectively, are
In a dc two-wire feeder, the voltage drop is 4%. What will be the transmission capacity of the feeder?
Vibratory feeder or toothed belt feeder as used to measure the quantity of the abrasive particles before mixing.
Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
Consider the following statements: 1. The voltage developed across the OFF switches of the half-bridge converter is the maximum dc-link voltage. 2. In the full-bridge converter, the voltage across the primary of the transformer is the dc link voltage. 3. The voltage developed across the OFF switches of the full-bridge converter is half the maximum dc-link voltage. Which of the above statements are correct?
In a voltage regulating system a rotating arm moves, depending upon the terminal voltage, across a set of contacts, short circuiting some part or more of the resistance inserted in the exciter field circuit. What type of voltage regulator is this?
