In Ferranti effect,Receiving end voltage is greater than
sending voltage,why? can anybody tell me the answer

Answer Posted / ashli

receiving end voltage becomes greater than sending end only
at light load or noload condn. most of our loads are
inductive, so power factor corecting equipments(say
capacitors) are connected in parallel to the line so that
the reactive power consumed by the load s supplied by the
capacitor. even though the loads are removed these
capacitive equipments are there. now the reactive power
supplied by the capacitor get added up. this s why the
receiving voltage becomes greater than supply end..
