The primary winding of a transformer has a terminal voltage of Vsource = 240 V. The turns ratio of the transformer is 50:200 (a=0.25); note that Np = 50 and Ns = 200. The impedances of this transformer referred to the primary side are Req = 0.05 ohm, Xeq = 0.225 ohm, Rc = 75 ohm, Xm = 20 ohm. A) Calculate the transformer impedances (Req, Xeq, Rc and Hm) referred to the secondary side. B) If the primary current of the transformer is Ip = 7.07<-36.8 A, what is the secondary current of this transformer? Do not ignore the excitation branch of the transformer in your calculations. C) Calculate the load voltage assuming that the load is connected to the secondary winding and assuming that the primary current is Ip = 7.07<-36.8 A.
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.
