railway RRB JE (CBT I + CBT II) Mock Test 2024 Power Systems Transmission and Distribution Underground Cables
What is the equation for the applied voltage between the core and the sheath for a Inters heath Grading cable, where R represents the radius of the outer sheath and gmax represents the peak value of electrical stress?
1
V =1.881 × R × gmax
2
V = \(\frac{R×g_{max}}{1.881}\)
3
V = \(\frac{1.881×g_{max}}{R}\)
4
V = \(\frac{1.881×R}{g_{max}}\)
