6 FAQs about [Electric utility terms and definitions power system]

What is a power utility?

An entity composed of two or more public power utilities that join together to own generation (and/or transmission) facilities, or parts of such facilities, in order to attain power costs that are lower than what could have been realized had they acted individually. 1,000 volt-amperes.

What does electric power system cover?

Covers electric power system components, electricity consumption, generation, transmission, distribution, electric utility operation, electric system control, power system reliability, government regulation, utility rate making, and financial considerations.

What is the difference between distribution system and distribution utility?

A distribution system, also known as an electric utility, is the substations, transformers, and lines that convey electricity from high-power transmission lines to ultimate consumers. A distribution utility, or Disco, is the regulated electric utility entity that constructs and maintains the distribution wires connecting the transmission grid to the final customer. See GRID.

What is electrical measurement?

The amount of electrical power dissipated or lost as heat during transmission, distribution, and utilization in an electrical system. The process of measuring electrical parameters, such as voltage, current, power, or energy consumption, to analyze and monitor electrical systems.

What is a standard electric utility frequency?

The standard electric utility frequency in the United States is 60 cycles per second, or 60 Hertz. FUEL -- A substance that can be used to produce heat. FUEL CELL -- A device or an electrochemical engine with no moving parts that converts the chemical energy of a fuel, such as hydrogen, and an oxidant, such as oxygen, directly into electricity.

What is electricity transmission?

Transmission refers to transporting electricity (typically over long distances) from the power plants where it is generated to the neighborhoods and cities where it will be used. For each mile electricity travels, some power is lost. Electricity is transmitted at high voltages to minimize this loss and make transmission more efficient.
