Answer / jagan

hi , when u keeps on increasing the voltageby 10% at one
instant ur flux densityincreased by 50% at this point u
say athis as knee point voltage.after u incresing it will
not increase bec this is saturate,,,,,
jagan(Tamilnadu)

Answer / shariff

This voltage is just like a diode knee voltage in CT, but at a specified rated current of the primary that CT after which the secondary will be constant irrespective of the changes in the primary.

Answer / sham

This is the voltage at which a CT becomes saturated. When a
CT becomes saturated it can no longer transform current. An
example of this rating would be C200, C800 etc... This
means that the CT will saturate near 200 Volts or 800 Volts
respectively.
