Temperature Rise on an Oil Filled Transformer
Temperature Rise on an Oil Filled Transformer
(OP)
The rated temperature rise is 55 deg C and 65 deg C.
First I don't really understand why the two ratings. I mean if heat is the enemy and this is a fan rating, it's still heating up 10 degrees higher - why is a higher rating allowed?
Second how can you tell if the transformer is running within its ratings...
Say it's zero deg C outside. And I read the gauge and it says its 55 deg C...then it's at rated temp right?

If that's the case...why don't they just rate it 105 deg C and be done with it?

If they just gave the number 105 you would never know what the ambient is limited to.
If the aforementioned transformer is located somewhere with a high ambient then you can not even run the transformer up to its specified load.
