Electrical distribution systems are an essential part of the electrical power system. In order to transfer electrical power from an alternating current (AC) or a direct current (DC) source to the place where it will be used, some type of distribution network must be utilized. Electricity is made at a generating station by huge generators. ... The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood.
