AFWF cooled transformers are often used in demanding applications like marine and oil & gas industry. By the use of AFWF cooling almost 90% of the heat losses can be transferred into the cooling water.
Three different types of LV/LV cast resin transformers have been tested in order to check their short circuit withstand capability according to the IEC Standards 60076.
The ability to withstand a short circuit is recognised more and more as an essential characteristic of power transformers. IEC60076-5 specifies short-circuit testing and how to check the withstand capability
