Answer Posted / viswanathan.

For obtaining a desired current at the utilisation end of a
cable irresponsible to the rated current carrying capacity
of a cable, many factors to be consider which tends to
reduces the current carrying capacity of a cable. viz
length of cable, connected equipment, inductive, capacitive
loads, etc. these factors will increases the actual current
and desired size of a cable.

please describe the Transformer setting, Motor setting, I/C setting, Tie setting

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
