A single engine or facility that produces electrical power by various means.

Power over Ethernet, or PoE, describes any of several standards or ad hoc systems that pass electric power along with data on twisted pair Ethernet cabling.

A loss of power to the end user.

Power-line communication carries data on a conductor that is also used simultaneously for AC electric power transmissionor electric power distribution to consumers.

A network of interconnected transmission lines for the delivery of electricity.

Defined as the ratio of the real or active power absorbed by the load to the apparent power flowing in the circuit.

Power engineering, also called power systems engineering, is a subfield of electrical engineering that deals with the generation, transmission, distribution, and utilization of electric power, and the electrical apparatus connected to such systems.

Power electronics is the application of solid-state electronics to the control and conversion of electric power.

The speed at which a wind turbine rotates must be controlled for efficient power generation and to keep the turbine components within designed speed and torque limits.

Electric energy consumption is the form of energy consumption that uses electric energy.

A power conditioner is a device intended to improve the quality of the power that is delivered to electrical load equipment.

A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath.

In physics, power is the amount of energy transferred or converted per unit time.

The pour point of a liquid is the temperature below which the liquid loses its flow characteristics.

The pound per square inch is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

The pound or pound-mass is a unit of mass used in the imperial, United States customary and other systems of measurement.

The pound of force or pound-force (lbf) is a unit of force used in some systems of measurement including English Engineering units and the foot–pound–second system.

A type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers.

In a potentiometric type of recorder, the direct drive of the marking pen is replaced with a servomechanism where energy to move the pen is supplied by an amplifier.

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
