Product Description
Protective current transformers are required to operate over a range of current many times the circuit rating 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 energise a protective relay, it must maintain its characteristic ratio up to some multiple fits rated current. This multiple, may be 5, 10, 20 or some even higher value and is know as the Accuracy Limit Factor?(ALF). Therefore, the selection of Protective Current Transformers in relation to accuracy class and ALF require a close examination of relay characteristic and circuit conditions which includes the relay burden and the pilot wire lead burden.
Customer Service is our first priority, It's our aim to exceed our clients' expections through dedication to service, quality and continuous improvement.
