What is power factor ?What are the benefits of improved
power factor & how. Please explain with examples.?
Answer Posted / ramesh
Generally power Factor are defined as the ratio between
Realpower(KW)/KVA (apprent power)
For ex- 8/10=.8
For kw= kva *.8
63*0.8=50.40kw
If power factor increses to .9 then
63*0.9=56.70
so the value kw increses if power factor increses
which indicates low current conjunction

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses? the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
