Power factor is the factor by which real power differ from
the apparent power.That is why it is called power factor.Real
power can NEVER BE GREATER than the apparant power.Since the
apparent power remains fixed,it is the power factor, which
decides the amount of real power calulation in the network.
That is why power factor is so much of importance in electrical
engineering.
Real power=(power factor)*(apparant power)
W = (pf) * (VA)

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
