  2. Losses in electrical systems - Wikipedia

    en.wikipedia.org/wiki/Losses_in_electrical_systems

    In an electrical or electronic circuit or power system part of the energy in play is dissipated by unwanted effects, including energy lost by unwanted heating of resistive components (electricity is also used for the intention of heating, which is not a loss), the effect of parasitic elements (resistance, capacitance, and inductance), skin effect, losses in the windings and cores of ...

  3. Dielectric loss - Wikipedia

    en.wikipedia.org/wiki/Dielectric_loss

    In electrical engineering, dielectric loss quantifies a dielectric material's inherent dissipation of electromagnetic energy (e.g. heat). [1] It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan( δ ) .

  4. Load-loss factor - Wikipedia

    en.wikipedia.org/wiki/Load-loss_factor

    Multiple empirical formulae exist that relate the loss factor to the load factor (Dickert et al. in 2009 listed nine [5]). Similarly, the ratio between the average and the peak current is called form coefficient k [ 6 ] or peak responsibility factor k , [ 7 ] its typical value is between 0.2 to 0.8 for distribution networks and 0.8 to 0.95 for ...

  5. Free-space path loss - Wikipedia

    en.wikipedia.org/wiki/Free-space_path_loss

    In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air). [1]

  6. Return loss - Wikipedia

    en.wikipedia.org/wiki/Return_loss

    Return loss is a measure of how well devices or lines are matched. A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss. From a certain perspective 'Return Loss' is a misnomer. The usual function of a transmission line is to convey power from a source to a load with minimal loss.

  7. Insertion loss - Wikipedia

    en.wikipedia.org/wiki/Insertion_loss

    In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). If the power transmitted to the load before insertion is P T and the power received by the load after insertion is P R, then the insertion loss in decibels ...

  8. Electron energy loss spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Electron_energy_loss...

    The low-loss spectrum contains the zero-loss peak (signal from all the electrons which did not loose a measurable energy) as well as the phonon [11] and plasmon peaks, and contains information about the band structure and dielectric properties of the sample. It is also possible to resolve the energy spectrum in momentum to directly measure the ...

  9. Loss factor - Wikipedia

    en.wikipedia.org/wiki/Loss_factor

    Loss factor may refer to: Loss factor , in real estate the percentage of the building's area shared by tenants or space that are dedicated to the common areas of a building used to calculate the difference between the net (usable) and gross (billable) areas.
