  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. 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 ...

  4. Steinmetz's equation - Wikipedia

    en.wikipedia.org/wiki/Steinmetz's_equation

    The equation is used mainly to calculate core losses in ferromagnetic magnetic cores used in electric motors, generators, transformers and inductors excited by sinusoidal current. Core losses are an economically important source of inefficiency in alternating current (AC) electric power grids and appliances.

  5. Loss of load - Wikipedia

    en.wikipedia.org/wiki/Loss_of_load

    Loss of load in an electrical grid is a term used to describe the situation when the available generation capacity is less than the system load. [1] Multiple probabilistic reliability indices for the generation systems are using loss of load in their definitions, with the more popular [2] being Loss of Load Probability (LOLP) that characterizes a probability of a loss of load occurring within ...

  6. Nonintrusive load monitoring - Wikipedia

    en.wikipedia.org/wiki/Nonintrusive_load_monitoring

    Nonintrusive load monitoring (NILM), nonintrusive appliance load monitoring (NIALM), [1] or energy disaggregation [2] is a process for analyzing changes in the voltage and current going into a house and deducing what appliances are used in the house as well as their individual energy consumption.

  9. Power outage - Wikipedia

    en.wikipedia.org/wiki/Power_outage

    Power outages are categorized into three different phenomena, relating to the duration and effect of the outage: A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power ...
