locate and test these faults?
2> why earth wire is provided on top throughout the
transmission line. why not only on towers? How much area it
can protect?
3> what r different types of transmission losses? How power
loss can be minimized?

1)i think that line to line faults happen in cables.by
noting the variation in current reading we can locate the
faults.
2) to save insulators and also to make insulators effective
between line and ground.
to save cost ,as providing earthing(coal & salt) to
particular tower for huge current is costly.
also huge current (in case of short circuit)can charged the
surrounding area.
how much area it can protect ? elabrote
3) refer some book
4) 8-10%
