Stray flux heating

Stray flux heating

Stray flux heating

(OP)
We have a 75MVA shell form power transformer.  The infrared shows the unusual heat pattern at the low part of tank.  Likely it's caused by the stray flux heating.

I am interested to know how other utilities' experience dealing with the stray flux heating.

1) will the tray flux heating limit the load?

2) We control the winding hottest spot temperature below 140 to avoid the gassing.  If the tray flux heating causes the tank overheated to, for example 150C, will there be the concern on the insulating being oil overheated or other problems?

3) Or waht is the main concerns about the stry flux heating?

THanks
