Current Transformer Fundamentals

Current transformer is an essential part of every Power System. We all might know the purpose of Current Transformer but we hardly understand how the current is flowing even though we know about polarity marks but it’s still confusing and complex to have all the fundamentals of current transformer on finger tips. This course combines brief introduction to Current Transformer with its main characteristic and applications. You will emerge with the knowledge in principles, working, applications, sizing of CT that empowers you to have strong grip on the fundamentals of Current Transformer.
