32Power (physics) — In physics, power is the rate at which energy is transferred, used, or transformed. For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts the more wattage, the more power, or what is the …
33Power flow study — In power engineering, the power flow study (also known as load flow study) is an important tool involving numerical analysis applied to a power system. Unlike traditional circuit analysis, a power flow study usually uses simplified notation such… …
34Power quality — In its broadest sense, power quality is a set of boundaries that allows electrical systems to function in their intended manner without significant loss of performance or life. The term is used to describe electric power that drives an electrical …
35Power conditioner — A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the “quality” of the power (see power quality) that is delivered to electrical load equipment. While there is no official definition… …
36Power quality — Le Power Quality n a pas de traduction fixe en français. On parle indifféremment de qualité de l’énergie, de l onde, du courant, de la tension ou de l électricité. Mais dans le milieu technique le terme Power Quality sera aussi utilisé ainsi que… …
37Power rating — In electrical engineering, the power rating of a device is a guideline set by the manufacturer as a maximum power to be used with that device. This limit is usually set somewhat lower than the level where the device will be damaged, to allow a… …
