  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. Performance and modelling of AC transmission - Wikipedia

    en.wikipedia.org/wiki/Performance_and_modelling...

    Phasor diagram of Ferranti effect in Cable. In electrical engineering, the Ferranti effect is the increase in voltage occurring at the receiving end of a very long (> 200 km) AC electric power transmission line, relative to the voltage at the sending end, when the load is very small, or no load is connected. It can be stated as a factor, or as ...

  4. OpenPDC - Wikipedia

    en.wikipedia.org/wiki/OpenPDC

    The phasor data concentrator runs as a Windows service. The service is responsible for managing the life cycle of adapters that create and process the streaming phasor measurements. Adapters are split into three layers: [3] [4] The input adapter layer is typically responsible for receiving data from an outside source such as a phasor ...

    en.wikipedia.org/wiki/Eagle_(program)

    EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features.

  6. Dia (software) - Wikipedia

    en.wikipedia.org/wiki/Dia_(software)

    Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.

  7. Phasor approach to fluorescence lifetime and spectral imaging

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

    Therefore, the phasor values of the pixels of an image with two lifetime components are distributed on a line connecting the phasors of τ 1 and τ 2. Fitting a line through these phasor points with slope (v) and interception (u) , will give two intersections with the semicircle that determine the lifetimes τ 1 and τ 2: [3]

  8. 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.

  9. Symmetrical components - Wikipedia

    en.wikipedia.org/wiki/Symmetrical_components

    Set of three unbalanced phasors, and the necessary symmetrical components that sum up to the resulting plot at the bottom. In 1918 Charles Legeyt Fortescue presented a paper [4] which demonstrated that any set of N unbalanced phasors (that is, any such polyphase signal) could be expressed as the sum of N symmetrical sets of balanced phasors, for values of N that are prime.
