Current Transformer's star point must face the protected object for the relay operation?..

Answer / hammad khan (university of wes

Not Necessary, Like in Siemens Siprotec Relay we can change the CT star point. There are two options, towards the time or towards the busbar. So however your CT star point is in the field you can configure it in the relay.

Sir we have 12.5 MVA(110/11KV) transformer (Y-Y) connected,which tripped showing earth fault,when we charged transformer it stood OK ,but on connecting 11 KV feeders it tripped showing earth fault.our service engineers found that the B phase and R phase phase connecting to neutral broken from HV OLTC(on load tap changer),and R phase and Neutral is ok.Dissolved gas analysis shows that accetline content is high,tan delta value is 12.My dout is it is an internal fault of transformer,why REF or diffrential relay is not acted?
