In this instrument the current comparer is set to zero magnetic flux, then the instrumenttransformer calibrator with the theory of measurement can measure the error of the current transformer.
Ct (Currenttransformer) Current transformers are instrument transformers used in conjunction with ammeters, control circuits and protective relaying. They usually have5 ampere secondaries.
