how netral CT is selected (including its details specification)

ABC, ABB, Mecon, dbpl, Shree Engineering, Tapasya Transformers,

8 29583

Different STANDARDS (BS, IS, IEC etc) gives different informations on CT specification. How they correspons w r t each other (i.e I mean to say BS provides "knee point voltage" but IS does not, then how can i select CT)
