I have to convert (0-50)mA to (0-1)A. The lower range of current required to be converted is from a current transformer of ratio 400/1. The CT actually to be installed was supposed to be 20/1. Instead, by some regrettable mistakes, it was wrongly wound to 400/1. Now the maximum primary current instead of 400A would be just around 20A. Hence for the protection relay to kick into action, this primary current of 20A has to transform into 1A. Instead I would be getting only around 50mA. Now if I have a circuit which could linearly transform (0-50)mA to (0-1)A then this should solve my problem.
