The power generation companies fundamentally engage themselves in creating electricity from the varied forms of energy. These commercial power unit generators are commonly constructed at a large scale, intended to operate round-the-clock. The step-up or step-down transformers are the most viable option for the power generation stations. The installation of mono-phase or three-phase transformers produces the Alternating Current (AC) at a frequency of 50Hz to 60Hz. The high-voltage channel generators are connected to the step-up transformers, linking them to the electrical substations of higher voltage.
