  2. Pacific DC Intertie - Wikipedia

    en.wikipedia.org/wiki/Pacific_DC_Intertie

    The Pacific DC Intertie (also called Path 65) is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). The line capacity is 3.1 gigawatts, which is enough to serve two to three million Los Angeles households and represents almost half of the ...

  3. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    The voltage changes due to the transition from line-to-line to line-to-earth, typically reducing a 22 kV grid to 12.7 kV SWER or a 33 kV grid to 19.1 kV SWER. The SWER line is a single conductor that may stretch for tens or even hundreds of kilometres, with a number of distribution transformers along its length.

  4. Stray voltage - Wikipedia

    en.wikipedia.org/wiki/Stray_voltage

    Stray voltage is defined as "A voltage resulting from the normal delivery and/or use of electricity (usually smaller than 10 volts) that may be present between two conductive surfaces that can be simultaneously contacted by members of the general public and/or their animals. Stray voltage is caused by primary and/or secondary return current ...

  5. Voltage drop - Wikipedia

    en.wikipedia.org/wiki/Voltage_drop

    In electronics, voltage drop is the decrease of electric potential along the path of a current flowing in a circuit. Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated. The voltage drop across the load is proportional ...

  6. Electrical resistance and conductance - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistance_and...

    Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...

  7. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the alternating current (AC) equivalent of the original Edison Machine Works three-wire direct-current system. Its primary advantage is that, for a given capacity of a distribution system, it saves conductor material over a single-ended ...

  8. WECC Intertie Paths - Wikipedia

    en.wikipedia.org/wiki/WECC_Intertie_Paths

    WECC Intertie Paths. A line on Path 65, part of the Pacific DC Intertie. The Western Electricity Coordinating Council (WECC) coordinates a number of high voltage power links in western North America. [1][2][3] These links, known as WECC Intertie Paths, are not necessarily single transmission line, rather they are interties between various areas.

  9. Josephson effect - Wikipedia

    en.wikipedia.org/wiki/Josephson_effect

    The effect is named after the British physicist Brian Josephson, who predicted in 1962 the mathematical relationships for the current and voltage across the weak link. [ 1 ] [ 2 ] It is an example of a macroscopic quantum phenomenon , where the effects of quantum mechanics are observable at ordinary, rather than atomic, scale.
