Hello, We have a 1000 kva ABB oil cooled transformer type 11kv to 430v, indoors. Please let us know if the transformer capacity could increase to 10% or 15% by installing air cool fans?
Yes, it is possible to increase transformer capacity with extra cooling system. ABB service can help you get a more precise answer based on the results of routine and temperature rise tests, and outline drawings on the existing transformer. A Dissolved Gas Analysis (DGA) report is also useful if available.
If you want to purchase a product, need any pricing information or need help or support from ABB, please contact your local partner.
