OIL LEVEL INDICATOR. By.. Uren Thummar Heema Dave. Abhishek Joshi Shruti Ghetiya. 1. Introduction. In conventions on Load Transformer Tap Changer there is production of Arc when changing the tapping of Transformer. And in large KVA rating of Transformer it is hard to quench the Arc. This major problem can solve in this thyristor based transformer tap changer.. Outline. Single-Ended Versus Differential Operation.
