Answer Posted / nithi
if power factor is leading ,this will leads the following.
system voltage increases-more pressure on
insulation-equipment life reduces-insulation break down-
over heating-over fluxing-core saturation-noise in core-
core over heating-may lead to ferroresonance(when resistive
loss is small)this will further complicate the situation-
harmonic production-increased THD-harmonic resonance-
penalty from EB-malfunction of control equipments & switch
gears-if overall system p.f. is leading,result in ferranti
effect-loss of power system costly apparatus-increased
losses-reduction in overall efficiency.
but actually,this will not happen in the power
system due to the presence of varios controls like
FACTS,shunt reactor,series reactor,synchronous condenser..

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
