CT Design

07/29/2013 10:47 AM

Hello,

I want to know the basic steps in CT design, I already have basic idea of determining knee point voltage using fault current. But no idea of transient part.

The impulse voltage withstand rating of a CT is defined by the standards you get the CT manufactured to. This is a good paper to read on CT design http://www.schneider-electric.com.au/documents/technical-publications/en/shared/electrical-engineering/breaking-techniques-switchgear/general-knowledge/ect194.pdf
