Answers were Sorted based on User's Feedback
Answer / dsrlsa
1. HVDC IS USED AS A TIE LINES BETWEEN TWO AC TRANSMISSION
LINES.
2. HIGH POWER TRANSMISSION IN LONG LINES.
3. IN SUBMARINES.
4. HVDC IS USED BECAUSE SKIN EFFECT IS ZERO. WHY, BECAUSE
FREQUENCY IS ZERO.

And all other tansmission losses is minimum rather than AC
transmission line such as faranty effect, corona effect and
capacitance property calculation will not be nagligible in
AC transmission.that HVDC is the best but not economical.

Spacing of Transformers ratings are 10kva,15kva,25kva,63kva,110kva,150kva .........so on Q) Why transformer are not manufactured having ratings in between or other than these standard ratings ?
Let's say I have 2 current carrying conductors C1 and C2 carrying currents of 5A and 10A. They are brought close to each other from a distance of infinity to a distance of 10cm away from each other - 1. What would be the values of current flowing in each conductor when (taking into account effects of interference of each conductor on the other) - a. The currents are AC b. The currents are DC c. C1 is AC and C2 is DC Please explain your answer with mathematical equations and formulas. Please specify the final numeric answer. Please make assumptions and clearly specify them.
