engineering recuitment GATE EE 2023-24 Test Series Power Systems Transmission and Distribution Substation
An electric train runs between two substations 6 km apart maintained at voltages 600 V and 590 V respectively and draws a constant current of 300 A while in motion. The track resistance of go and return path is 0.04 Ω/km. The minimum potential occurs at
1
a distance of 4.675 km from the substation A
2
a distance of 3.425 km from the substation B
3
a distance of 2.575 km from the substation B
4
a distance of 1.325 km from the substation A
