Convection may happen in at all scales larger than a few atoms. There are a variety of circumstances in which the forces required for convection arise, leading to different types of convection, described below. In broad terms, convection arises because of acting within the fluid, such as gravity. Natural convection is a flow whose motion is caused by some parts of a fluid being h. [pdf]

By expanding a to show the positive sequence, negative sequence, and zero sequence impedances of , and other devices including and , analysis of such unbalanced conditions as a single line to ground short-circuit fault is greatly simplified. The technique can also be extended to higher order phase systems. Physically, in a three phase system, a positive sequence set of currents produces a normal rotating fiel. .
In a three-phase system, at least two transducers are required to measure power when there is no neutral, or three transducers when there is a neutral. states that the number of measurement elements required is one less than the number of current-carrying conductors. [pdf]
