Answer / kalaianbu

when the ac transmision voltage goes above the particular
value,the corona effect will occur. the corresponding value
of voltage is called as critical disruptive voltage.

Answer / thileepan.p

hi,
Actually tat term is calld "crictical distruptive
voltage".it deals with carrona loss.in transmission line if
we allow high ac voltage more than tis "crict distr
voltage" means it ill leads to carrona effect.

Answer / v.selvakumar

voltage at which insulation properties will loss is called
disruptive voltage

Answer / chandan jha

It is the minimum phase to neutral voltage at which cornro
occurs.It is multiple of break down strength of air , it is
betbeen two wire hving large potential diffrence and less
spaced apart

vc = g.rlog(d/r)

here vc is C.D.voltage , g is breakdown strength of air , d
is distance betbeen conductors, r is radia of conductor .

Answer / guest

desruptive means the highly tensile strength
