Current limit resitor(CLR) will make the grounding relay and zero voltage meter operate due to the current which in a djusted primary neutral side current when fault. And it will be connected with 3ry side of GPT between terminal “ a ” and terminal “ f ” and then it restrains the 3ry harm once voltage and abnormal potential.

※비 고 1. GPT의 최고전압이 1분이상 인가되면 CLR이 소손될 우려가 있습니다. 2. 저압 GPT인 경우 3차 정격부담의 70%~100%가 되도록 CLR 저장값을 조정해서 사용하시기 바랍니다. ※
Remark 1. If max 3ry voltage of GPT is on the CLR during 1 minute over. the CLR may be fired. 2. In case of low voltage G.P.T, Please adjust the value of CLR to 100~70% loading of rating burden on FPT 3ry open terminal
