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

Their use enables circuits to be kept in service until times when faulted or overloaded parts of a network must be disconnected to ensure that healthy equipment does not suffer consequential

Their application to overhead lines and cables was described in Chapter 9, in which it was shown that there are factors which limit the lengths of circuits which may be protected when the comparisons are effected over interconnecting co

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