It depends on the nature of the transmission line mostly under a fault it is the inductance that will be limiting the fault current so your power factor would be quite low. The exact number would change from line to line. During a fault (say three phase fault for simplicity), the power factor will drop to the line angle (assume no, or very little fault resistance). On EHV systems, this is in the 80 - 88 degree range (typically). On VHV, it is often in the 70-80 degree range. A line angle of 90 degrees is a pf of 0, so to convert between this line angle and power factor: pf = cos (line angle). As voltage gets lower, the assumption of no fault resistance becomes less valid, and the line angle becomes less (increased power factor). The lowest VHV line angle I've seen is in the 60-70 degree range. I've seen 40-60 on HV, and as low as 30 degrees (.86 pf) on underground cabling.
It could be a phase to phase, ph to neutral or earth fault. In single ph wiring ph to ph exhibits no short ckt faultAnswerYes, but you have got the terminology wrong. There is no such thing as 'phase-to-phase', the correct term being 'line-to-line'. So you can have a short circuit as a result of a line-to-line fault, a line-to-neutral fault, or a line-to-earth fault.

The distance relay trips when a fault occurs at a distant or a remote place in the electric transmission line. There is a mechanism based on the impedance calculation of the distance of the transmission line after which it is accurately known where the fault has taken place. Thus the distance protective relay can trip the circuit & prevent the fault to be carried further and also can indicate the location of the fault.
The function of a neutral earth resistor is to limit any fault current resulting from fault between a line conductor and earth.
Kobe is on the nojima fault line
It's hard to say why people would knowingly build on a fault line. Usually it seems to be a case of people assuming that nothing bad will happen.
England is not on or near a fault line.
They Can occur anywere a Fault Line is on Earth They happen when earths crust releases and the Fault Line send out Energy =p
earth quakes happen because of the fault line. Underneath the suface the plate are moving

There are different plates near India, so there would be a fault line, or maybe a lot.
no only on or close to the edges of a fault line or tectonic plate
That would be the San Andreas fault line.
Yes San Andreas has had an earthquake in fact it has been a lot of them San Andreas even has a fault line named after it (The San Andreas fault line is actually a visible crack in the ground) and a lot of earth quakes happen upon a fault line.
He would oft apologize for things that were no fault of his own. The fault line often produced violent earthquakes.
