A student is planning to install a photo-voltaic system in a location where the peak sun hours is 4 hours per day. He assumes that the electrical energy requirement for one day is 6 kw-hr. In designing the PV system, he considers using solar panels each with rated power of 200 W and voltage of 12 volts. The system efficiency is 75%. a) Calculate the number of solar panels he needs to buy. (2 marks) b) What is the daily capacity factor for this system? (2 marks) c) Is the capacity factor for this solar PV system low or high? Why? (1 mark) d) What is the total current and voltage for the system if the PV panels are to be

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.
