"A transformer substation is a location where electric power is converted from bulk power to local power or vice versa."

"Without transformers the electrical energy generated at generating stations won’t probably be sufficient enough to power up a city."

"A transformer is a device that can change the potential difference or voltage of an alternating current (ac)."

"Station transformer fed supplies are not protected from step or rapid changes in voltage on the grid system, and their voltage profile closely follows that of the grid."

"The power transformer is usually operated in full load because it is designed to have high efficiency at 100% load. On the other hand, the Distribution transformer has high efficiency when the load stays between 50% and 70%. So, distribution transformers are not suitable to run at 100% load continuously."

"A step-up transmission substation receives electric power from a nearby generating facility and uses a large power transformer to increase the voltage for transmission to distant locations"

"A high voltage transformer is a kind of electrical transformer. The basic function of an electrical transformer is to transform electrical energy into usable forms. When it transforms a high number of electrons to a low number or vice versa, electricity that is produced as a result can then be transported. The strength of electrical transformers varies from those needed for individual electricity production to large transformers used in power plants, which have outputs of many tons and kilotons."
