Current Transformer/electric current/Protect current transformer

1.Required to operate over a range of current
2.electric current transformer
3.Protective current transformer

Discription

Protective current transformer are required to operate over a rang of current many times the

circuit rating and is frequently  subjected to as measuring   current  transformer .when a current  transformer   is ued   to energise a protective relay .it must mainintain its characteristic ratio up  to  some  multiple  of its rated current,.this  multip may be 5, 10, 20 or some even higher value and is know as the ccuracy Limit Factor?(ALF). Therefore, the selection of Proterctive Current Transformers in relation to accuracy class and ALF require a close examination of relay characteristic and circuit conditions which inclues the relay burden and the pilot wire lead burden.
