Answer Posted / gk
There is no increase of reactive power as such because of
ferranti effect which happens under light load or no-load
situation. Suppose if there is no load, effect of line to
ground capacitance will come into picture. So receiving end
voltage Vr = Vs-(I*jXl)
= Vs-((-Vs/JXc)*JXl) assume I = Vs/(-JXc)
Vr=Vs(1+..)
therefore Vr > Vs under ferranti effect
Any additions or comments are welcome.TQ

design of IGBT firing circuit for 11KV
at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
