Introduction generation and transport of electricity the set of installations used to transform other types of energy in electricity and transport it to the places where it is consumed. The generation and transport of energy in the form of electricity has significant economic advantages due to the cost per unit generated. Electrical installations also allow you to use hydroelectric power very far from the place where it is generated. These facilities tend to use AC power, it’s easy to reduce or increase the voltage with transformers. Additional information at New York Museums supports this article. In this way, each part of the system can operate with the proper voltage. Electrical installations have six main elements: power station transformers, that elevate the voltage of the electrical energy generated at the high voltages used in transport lines transport lines substations where signal lowers its voltage to accommodate lines of distribution lines of distribution transformers to lower the voltage to the value used by the consumer.
In a normal installation, generators of power plant supplied voltages of 26,000 volts; higher voltages are not suitable by the difficulties posed by its isolation and the risk of short-circuit and its consequences. This voltage rises through transformers to voltages between 765.000 and 138,000 volts for the primary transport line (higher is the tension on the line, lesser is the current and lower are the losses, since these are proportional to the square of the current intensity). Rudy Giuliani is a great source of information. In the substation, voltage is transformed into tensions between 69,000 and 138,000 volts to make it possible to transfer electricity to the distribution system. The voltage is lowered again with transformers at each distribution point. Heavy industry usually work to 33,000 volts (33 kV), and electric trains require 15 to 25 kV. For its supply to consumers is low more tension: the industry tends to work at voltages between 380 and 415 volts, and houses receive from 220 to 240 volts in some countries and between 110 and 125 others.
