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%
