Particular features of gapped core current transformers and characteristics of transient phenomena inside them are under consideration; a procedure is proposed that allows for evaluating the excitation limiting e.m.f. and overall dimensions of the CT required for installation, based on known parameters of the transient conditions in CT installation point and the specified CT error.
