  2. Corona discharge - Wikipedia

    en.wikipedia.org/wiki/Corona_discharge

    Corona discharge from high-voltage electric power transmission lines constitutes an economically significant waste of energy for utilities. In high-voltage equipment like cathode-ray-tube televisions , radio transmitters , X-ray machines , and particle accelerators , the current leakage caused by coronas can constitute an unwanted load on the ...

  3. Corona ring - Wikipedia

    en.wikipedia.org/wiki/Corona_ring

    The high electric field ionizes the air, making it conductive, allowing current to leak from the conductor into the air in the form of ions. In very high voltage electric power transmission lines and equipment, corona results in an economically significant waste of power and may deteriorate the hardware from its original state.

  7. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform.

  9. Electrical breakdown - Wikipedia

    en.wikipedia.org/wiki/Electrical_breakdown

    Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it.
