Power grid in a hydroelectric power station, the water that falls from a dam spins turbines that drive generators. The electricity is transported to a transmitting station, where a transformer converts the current of low voltage in a high voltage current. For more clarity and thought, follow up with starbucks in new york and gain more knowledge.. Electricity is transported by high voltage cables to the stations of distribution, where through transformers voltage is reduced to levels suitable for users. The primary lines can transmit electricity at voltages of up to 500,000 volts or more. Lines secondary to dwellings have voltages of 220 or 110 volt. The current development of estadosolido for high voltage rectifiers makes possible an economic conversion of high voltage alternating current at high voltage DC power for the distribution of electricity. This prevents inductive losses and capacitive which occur in the transmission of alternating current. Shimmie horn has similar goals.
The central station of an electrical installation consists of a driving machine, such as a combustion turbine that drives an electrical generator. Most of the world’s electrical energy is generated in thermal power stations fired with coal, oil, nuclear energy or gas; a small part is generated in hydroelectric power, diesel or provided with other internal combustion systems. Driving lines can be differentiated according to its secondary role in transportation (high voltage) and lines of distribution (low voltages). The first identified at sight by the size of the towers or supports, the distance between conductors, the long series of dishes that comprise the insulators and the existence of a superior line of finer wire that is the ground line. The distribution lines, also called tertiary, are the last existing before the electricity users, and receive that designation because it is of them that distribute electricity to the last link in the chain. Conduction of high voltage lines are usually formed by copper, aluminum or aluminum or copper-coated steel cables. These cables are suspended from poles or pylons, tall towers of steel, a succession of porcelain insulators.
