All power systems have one or more sources of power. For some power systems, the source of power is external to the system but for others, it is part of the system itself—it is these internal power sources that are discussed in the remainder of this section. Direct current power can be supplied by batteries, fuel cells or photovoltaic cells. Alternating current power is typically supplied by a ro

Utility Power Transmission and Distribution Systems

The amount of current changes inversely with the amount of voltage for a given power level. In addition, increasing the transmitted voltage lowers the power losses between the utility generator and the final delivery point. Doubling the transmitted voltage can reduce the power loss by up to 75%.
