(OP)
Can anybody explain what is dimensional factor in Current transformer?what is its significance?what is the effect on CT saturation with low/high Kxetc.

This is a link with an explanation http://www.skm.com/newsletters/winter99.pdf - see page 2.
If you do some more googling you wil find further details
RE: CT Dimensional factor Kx
The dimensioning factor normally caters for this. It's actual value depends on what equipment is connected to the CT.
If you need a more detailed response, I suggest a more detailed question !!
RE: CT Dimensional factor Kx
one having Kx 26 & other having 75
both are having Knee point #voltage 1600 (Name plate),
actual 1800&2400respectively,
one is STR=26.1 other 40KA
during a fault of 34KA what will the difference in behaviour of CTs ,is there any chance of CT saturation?
here we came across with question of Kx and Ktd(Over dimensioning factor)can you explain?the Cts are used in Bus Differential protection,oneof the CT is suspected to have malfunctioned during a flashover fault.
RE: CT Dimensional factor Kx
The person specifying the CT in the first place must have taken all of this into consideration.
Are both CTs (per the N/P) supposed to be identical??
