Such transformers are normally used to step down high currents flowing in their primary windings to lower levels suitable for feeding to measuring and protective equipment. Isolation of the latter equipment from the primary circuits is ensured by t

Such schemes cannot however operate extremely rapidly because time must be allowed for the interchange of signals between the ends of the protected lines.
