Onan cooled transformer
WebThese transformers are cool- ing class OA/FA transformers. Some transformers are cooled by natural convection below temperature T1, turn on one stage of fans at a higher temperature T2 and turn on a second stage of fans at an even higher temperature T3. These transformers are cooling class OA/FA/FA transformers.
