15va 1200/5a PR series Protective Current Transformer For Malaysia Market
Description :
Protective current transformer are required to operate over rated current many times and is frequently subjected to conditions greatly exceeding those which it would be subjected to as a measuring current transformer. When a current transformer is used to energize a protective relay, it must maintain its characteristic ratio up to some multiple of its rated current. This multiple maybe 5, 10, 20 or some even higher value and is known as the "Accuracy Limit Factor"(ALF). There for, the selection of Protective Current Transformer in relation to accuracy class and ALF require a close examination of relay characteristics and circuit conditions which includes the relay burden and the pilot wire lead burden.
