GATE 2024 Power Systems Foundation Quiz 40

A uniformly distributed dc two wire distributor 100 m long is loaded at 1A/m. Go and return resistance of the loop is 0.05Ω/km. if the distributor is feed at both ends at the same voltage. The maximum voltage drop is _______ mV.

Which of the following statement is NOT correct?

Why is ring main distribution system preferred to a radial system?

1) Voltage drop in the feeder is less

2) Power factor is higher

3) Supply is more reliable

Select the correct answer using the codes given below:

Consider a DC distributor a b c d e f in the ring main is fed from one source at 150 V and load is shown in figure. Find the minimum potential in the ring main? Resistance of the feeder is 0.2 Ω/km.

The two ends of the feeder are fed by voltage source such that V_A = 5+V_B

The resistance of each conductor is 0.2 Ω/km. Find the current (in A) fed at end B.
