摘要: By calculating power losses of transformers in different running modes, the important function of economical running in reducing loss and the energy saving of transformers are discussed.关键词: transformer power loss economical running energy saving with loss reduction ...
Advantages of Planar Transformer -Low profile -Low leakage inductance -Low eddy current losses -High efficiency -High power density -High process capability -Unrivalled repeatability -Multiple Windings Options -Multiple Topologies -Very good thermal performance ...
On-Load Tap Changer (OLTC) s are widely used in HV/MV transformer applications due to their low current levels. While line voltage regulators help locally improve voltage profile and reduce losses in distribution line, OLTC has a wider effect [72]. Flexible AC Transmission System (FACTS) ...
The amount of energy necessary to have a good thermal comfort in a building depends not only on its volume, orientation, rigor of the climate and temperature to be maintained, but also on the heat losses or gains that the building has through its external envelope, which determine the energy...

the Gilbert–Elliott channel appears to be a more realistic model in the description of data losses due to imperfect communications, since it takes influences of the previous states of a communication network on its current states, which is closer to actual situations. A cost is that this model...
