what ever be the power generated by the generator, that is
used by the consumers i. e.lighting loads,ind.motors,arc
furnaces and all these loads works on lagging power factor
so if it is zero means no reactive power flow ie.load
didn't get reactive power so it will not run or work
satisfactorily. 1) if we think about gen,then it is under
excited condition for generator so terminal voltage of
generator will decrease and current will increase.2)we know
all the generator are connected together with grid if
reactive power flow of any one generator become zero then
it has adverse effect on other generators,resulting in
power loss,heating effect and many more.
