(b) An impulse voltage generator as shown in Figure 1 is used to conduct an impulse test on switchgear. The generator has five (5) stages with each capacitor rated at 50nF, 125kV. C, is the total generator capacitance. The load capacitance, C2 is in the range of 500pF ~ 1500pF. Determine; i. the series resistor (R1) and the discharge resistor (R2) needed to produce 1.2/50µs impulse wave. ii. the maximum output voltage of the generator if the charging voltage is 120 kV.
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.
