Energy is required to change the phase of a substance, such as the energy to break the bonds between molecules in a block of ice so it may melt. During a phase change energy my be added or subtracted from a system, but the temperature will not change. The temperature will change only when the phase change has completed.
When three-phase is needed but only single-phase is readily available from the electricity supplier, a phase converter can be used to generate three-phase power from the single phase supply. System measurements. It is possible to measure the power in a three-phase system using two transducers when there is no neutral, or three transducers when there is neutral. Blondel's theorem states that the number of measurement elements required is one less than the number of current-carrying conductors ...
