Large aluminium distribution transformer

Abstract

Through long global experience and test results it has been described that the aluminium wound large distribution transformers are equally good like copper wound transformers. Performance and life of transformers are same and also the parameters can be maintained identical like copper wound transformers. There will be nominal dimension increase which are normally not critical issue. The biggest advantage in today's economic turmoil, cost at initial investment can be reduced to approximately 15%. The case has been demonstrated with 950 kVA transformers conducting dynamic short circuit test at ERDA.
