what is Real power and Reactive power ? what is difference
between them ?
Answer Posted / s.k.
Real power (Watt) is the power useful in the network , it
is : P = S x P.F.
where P = real power (W )
S = Apparent power ( VA )
P.F. = Power Factor = cosine the angle between P,S
The reactive power ( Q ) , produced by capacitabce in the
network ( under ground cables ) and should be elemenated as
much as possiable
Q = S x sin theeta
Theeta = sine the angle between P,S
