Question 4 a) A 3-phase, single circuit transmission line, is given with the length somewhere in the range of 250 km - 400 km long. If the transmission line is rated for 220 kV and has the parameters, R = 0.1 ohms/km, L = 1.26 mH/km, C = 0.009 µF/km, and G = 0, analyze the scenario and determine; (i) the surge impedance (ii) the velocity of propagation neglecting the resistance of the line. If a surge of 150kV strikes at one end of the line, determine; (ii) the time taken for the surge to travel to the other end of the line.
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.
