  2. Tap changer - Wikipedia

    en.wikipedia.org/wiki/Tap_changer

    For example, in power distribution networks, a large step-down transformer may have an off-load tap changer on the primary winding and an on load automatic tap changer on the secondary winding or windings. The high voltage tap is set to match long term system profile on the high voltage network (typically supply voltage averages) and is rarely ...

  3. Ponzo illusion - Wikipedia

    en.wikipedia.org/wiki/Ponzo_illusion

    Another explanation is the "framing-effects hypothesis", which says that the difference in the separation or gap of the horizontal lines from the framing converging lines may determine, or at least contribute to the magnitude of the distortion. The Ponzo illusion is one possible explanation of the Moon illusion, as suggested by Ponzo in 1912. [3]

  4. Line–line intersection - Wikipedia

    en.wikipedia.org/wiki/Lineline_intersection

    Two intersecting lines. In Euclidean geometry, the intersection of a line and a line can be the empty set, a point, or another line.Distinguishing these cases and finding the intersection have uses, for example, in computer graphics, motion planning, and collision detection.

  5. Talk:Tap changer - Wikipedia

    en.wikipedia.org/wiki/Talk:Tap_changer

    A tap-changer is an electrically operated (usually) mechanical device used for changing the tapping usually on the primary of a high voltage transmission transformer in order to alter the voltage at the transformer secondary for the purpose of regulation of the voltage at the load (consumer) end of the line. This sentence is barely comprehensible.

  6. Hyperbolic geometry - Wikipedia

    en.wikipedia.org/wiki/Hyperbolic_geometry

    Two intersecting lines have the same properties as two intersecting lines in Euclidean geometry. For example, two distinct lines can intersect in no more than one point, intersecting lines form equal opposite angles, and adjacent angles of intersecting lines are supplementary. When a third line is introduced, then there can be properties of ...
