  2. Phasor - Wikipedia

    en.wikipedia.org/wiki/Phasor

    Phasor notation (also known as angle notation) is a mathematical notation used in electronics engineering and electrical engineering.A vector whose polar coordinates are magnitude and angle is written . [13] can represent either the vector (⁡, ⁡) or the complex number ⁡ + ⁡ =, according to Euler's formula with =, both of which have magnitudes of 1.

  3. Phasor measurement unit - Wikipedia

    en.wikipedia.org/wiki/Phasor_measurement_unit

    Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.

  4. Phasor approach to fluorescence lifetime and spectral imaging

    en.wikipedia.org/wiki/Phasor_approach_to...

    Changing the spectral width from zero to infinity moves the phasor toward the center. This means that the phasor for the background signal, which can be considered a spectrum with infinite spectral width, is located at the center of the phasor with coordinates (0,0). Behavior of the phasor for different spectral widths.

  5. Leading and lagging current - Wikipedia

    en.wikipedia.org/wiki/Leading_and_Lagging_Current

    A simple phasor diagram with a two dimensional Cartesian coordinate system and phasors can be used to visualize leading and lagging current at a fixed moment in time. In the real-complex coordinate system, one period of a sine wave corresponds to a full circle in the complex plane.

  6. Symmetrical components - Wikipedia

    en.wikipedia.org/wiki/Symmetrical_components

    Decomposing the voltage phasor components into a set of symmetrical components helps analyze the system as well as visualize any imbalances. If the three voltage components are expressed as phasors (which are complex numbers), a complex vector can be formed in which the three phase components are the components of the vector.

  7. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    Inspection of a phasor diagram, or conversion from phasor notation to complex notation, illuminates how the difference between two line-to-neutral voltages yields a line-to-line voltage that is greater by a factor of √ 3.

    A phasor for I/Q, and the resultant wave which is continually phase shifting, according to the phasor's frequency. Note that since this resultant wave is continuously phase shifting at a steady rate, effectively the frequency has been changed: it has been frequency modulated.
