Fundamentals of Power System protection by Y.G.Paithankar ...· 1.7.1 Current Transformer The current transformer has two jobs to do. Firstly, it steps down the current to such levels that it can be easily handled by che relay current cod. The standard secondary current ratings used in practice are 5 A and 1A. This frees the relay designer from the actual value of primary current.
