The following values were seen in the measurements made separately by the primary and secondary of a 220/270 V phase transformer. R1 = 4 ohms, X1 = 4.6 ohms, R2 = 0.89 ohms, X2 = 1.79 ohms; R2T = 8.7 ohms, X2T = 8.8 ohms (total values measured on the secondary side), Xm = 60 ohms, Rfe = 750 ohms, (using a T-type equivalent circuit) a.) Primary and secondary currents and their phase angles b.) Active and reactive powers drawn by the transformer from the network. please solve them all, thanks
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.
