We have a 15 MVA, 33/6.6 KV transformer with internal Cts on 6.6 KV side (oil immersed CT). s*
.We found excessive overheating on CT's secondary connection on marshalling box *
CTs were originally not used and it's terminals were shorted but connection might have loose.
Transformer was taken out of service and CTs secondary terminal jumpers is verified again , and put transformer in service again.
سؤالي : هل في اي مشكله علي وضع المحول في الخدمه وازاي اطمن ان ال CTs مأثرتش علي الزيت او المحول من الداخل
