Type test:
It is conducted on first prototype of product to confirm
the design specifications.This test is not repeated on
other products of same type.e.g, temp rise test

Routine test:
It is conducted on each product manufactured to confirm
proper maufacturing of each and every units.This test is
essential to be performed on each unit before distaching
the product to site.

I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.
