Answer Posted / najeeb khan
reactive power remains same in both cases. mathematically we
just write Legging or leading. actually reactive power is an
undesirable phenomenon whether it is legging or leading.
the reason we think that leading pf is good is that it
neutralizes the legging reactive pf,(as our power system
mostly consists of legging pf equipments ).
