I like to add a bit more to Gnd Kumarans answer.
INCLUDE LOAD CURRENT, LENGTH,VOLT DROP AND
1)Type of cable cu/ al, underground, pvc etc
2}how you want to lay eg overhead line, conduit,
underground. cable tray, trunking.
3)if necessary type of protection you are giving
than with the help of the manufacturers cable catalogue you
can safely determine the cable size.
there is no fast rule to say cu cables carry 2.;5 times &al
cables carry 1.5 times the cable size to determine the cable
size.

please send me previose rrb junior engineer qustion papers
i am an maintenance engineer. one distribution board have 5 feeder. recently its ELR trips frequently, but it take some times after trip( 10min,20min..)but 3 feeder no load. two feeder only loaded. i checked one feeder IR value all values are above 50Mohm.but B phase to Earth is only 9Mohm.any problem about low value
I need a formula to calculate the size of cable as per load but in the terms of length. Please Reply me as i search lot of sites but i did not get the answer.

1. A 380 / 220 V r.m.s. 3-phase 4-wire circuit carries loads of 8 + j8.1 ohm; 4 + j4.1 ohm; and 2 +j2.1 ohmin the three phases respectively. The length of the circuit is 100 m, and the resistivity of the phase conductors is 0.0005 Ω/m. The neutral conductor is of the same size as the phase conductors. a) Select a reference angle 0for the first phase. Then write down the three phase voltages in both polar format and complex number format. b) Make appropriate assumptions, and take temperature effects on resistance is insignificant. Calculate the currents in the three phases. (Note: Determine conductor resistance, and apply Kirchhoff’s Voltage Law) Based on the result, suggest a main switch rating for the circuit. c) Show your preferred direction of neutral current in a diagram, and then determine its value. (Note: Apply superposition principle, and Kirchhoff’s Current Law) Use its magnitude to show that in this circuit, the unbalanced load may increase the voltage drop in some of the phases. (Note: Also observe the common volt drip in neutral) State your assumptions, if there are any. d) Suddenly the neutral wire of the circuit is broken. Estimate the new currents in the first phase, i.e. Phase L1. State your assumptions, if there are any.
is there any device that works properly accept relay, it may be fuse but if i want fuse of 33kv 300 amp it is avaliable, pls give me details

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
