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.

9.In AC circuits, power consumed is
ZL= 50 + j60 ohm
ZS= j25ohm
By taking Zbase = 100 ohm, find Vs (p.u), Zs(p.u), ZL(p.u)
A.
Zs(p.u) = j0.20 p.u
ZL(p.u) = 66.42<390 p.u
Zs(p.u) = j0.25 p.u
ZL(p.u) = 42.96<730 p.
Zs(p.u) = j0.25 p.u
ZL(p.u) = 0.781<50.20 p.u
13. Which of following equivalent per unit is inaccurate?
A /Pp.u = p actual / p base per unit
B /Vp.u = V acual / V base per unit
C / Ip.u = I actual / I base per unit
