Transformer Protection
Transformer Protection
(OP)
Dear All,
in a transformer protection graph with a fuse.
I have seen in most cases that transformr damage curve crosses fuse curve around 50 sec.
What's the concept behind this?
I have reviewd some articles,but couldn't find anything regarding this matter.
Thanks

A colleague suggested changing the breaker trip setting to 2000A from 3000A and so we need to change the CT ratio too!
I appreciate your feedback on this.
