phase step down transformer 1200 KVA , 11000/2200 V, 50 Hz .The resistance /phase and leakage reactance/phase of the primary winding are 0.8Ω and 4.8Ω and the corresponding values for the secondary winding are 0.01Ω and 0.06Ω respectively if the primary winding is connected in delta and secondary in star calculate: i)The voltage to be applied at normal frequency to the primary to circulate full-load through it when the secondary is short-circuited ii) The full load copper loss
Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
