  2. Ferroresonance in electricity networks - Wikipedia

    en.wikipedia.org/wiki/Ferroresonance_in...

    [8] [9] The transformer must be operating close to its saturation point, [10] at which a real transformer's leakage inductance decreases dramatically. [ 11 ] Following perturbation, the transformer oscillates in and out of the saturated and unsaturated modes of operation each cycle , such that the cycle- average inductance cancels out the power ...

  3. Voltage spike - Wikipedia

    en.wikipedia.org/wiki/Voltage_spike

    In electrical engineering, spikes are fast, short duration electrical transients in voltage (voltage spikes), [1] current (current spikes), or transferred energy (energy spikes) in an electrical circuit. Fast, short duration electrical transients (overvoltages) in the electric potential of a circuit are typically caused by [2] Lightning strikes ...

  4. Snubber - Wikipedia

    en.wikipedia.org/wiki/Snubber

    This transient can be a source of electromagnetic interference (EMI) in other circuits. Additionally, if the voltage generated across the device is beyond what the device is intended to tolerate, it may damage or destroy it. The snubber provides a short-term alternative current path around the current switching device so that the inductive ...

  5. High-voltage direct current - Wikipedia

    en.wikipedia.org/wiki/High-voltage_direct_current

    Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. [1]

  6. Transient response - Wikipedia

    en.wikipedia.org/wiki/Transient_response

    Damped oscillation is a typical transient response, where the output value oscillates until finally reaching a steady-state value. In electrical engineering and mechanical engineering, a transient response is the response of a system to a change from an equilibrium or a steady state. The transient response is not necessarily tied to abrupt ...

  7. Transient recovery voltage - Wikipedia

    en.wikipedia.org/wiki/Transient_Recovery_Voltage

    Examples of TRV waveshapes. A transient recovery voltage (TRV) for high-voltage circuit breakers is the voltage that appears across the terminals after current interruption. It is a critical parameter for fault interruption by a high-voltage circuit breaker, its characteristics (amplitude, rate of rise) can lead either to a successful current interruption or to a failure (called reignition or ...

  8. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    An example of inrush current transients during capacitor bank energization. Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on.

  9. Single-ended primary-inductor converter - Wikipedia

    en.wikipedia.org/wiki/Single-ended_primary...

    The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential at its output to be greater than, less than, or equal to that at its input. The output of the SEPIC is controlled by the duty cycle of the electronic switch (S1).
