A 250 kVA transformer is at full load with a power factor of 0.8 lagging. The power factor is to be connected to 0.9 lagging by parallel capacitor. (a) What kVAR of capacitor does this require? (b) What kW of new load at unity power factor may now be added without exceeding the rated transformer kVA? (c) a new load with a power factor of 0.5 lagging is added to the system after the capacitors have been installed. What kVA of this load may be added without exceeding the rated transformer kVA?
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.
