Transformer Cooling
Transformer Cooling
(OP)
My client has a 7.5/10MVA ONAN/ONAF 69kV/25kV station transformer operating at 10.1MVA. They want to add load of 0.6MVA. I am considering auxiliary cooling. Does anyone have experience with portable style oil coolers and are they effective?
Thanks
Thanks

Your Trx 10MVA is based on what oil Temp.55/65?
You may want to ask equipment specialist to do a real time rating study of the Trx to see the maximum rating the Trx can get before you decide to install additional cooling fan.
