ABB company manufactures three phase, 10 kVA, 240 V, 60Hz, 6 pole wye connected synchronous generator. The generator is connected to an infinite bus at rated voltage. The generator has synchronous reactance of 2.0 ohms/phase and negligible stator resistance and is delivering the rated power at 0.9 power factor lagging. Determine the following: a. Stator current b. Excitation voltage (per phase and line to line) c. What is the pullout torque (maximum torque) delivered by the generator?
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.
