Hi Everybody

I hope someone could clarify me on this issue.

We have an ACS 800 ABB Drive (cabinet built) for 400 kW motor. When it is powered only, there is a transformer Trafomic TNR 26492 that smells (like burning).

I would like to know for what purpose is this transformer.

If it operates for 10 mins, we get alarm ACS 800 temp i.e. IGBT overheat.

Can someone suggest what test and action may be required

Thanking you beforehand.
