    V svc is the rms value of the line-to-line busbar voltage to which the SVC is connected C tsc is the total TSC capacitance per phase L tsc is the total TSC inductance per phase f is the frequency of the AC system The TSC forms an inductor-capacitor (LC) resonant circuit with a characteristic frequency of :

  3. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.

  4. Static VAR compensator - Wikipedia

    en.wikipedia.org/wiki/Static_VAR_compensator

    In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [ 1 ] [ 2 ] SVCs are part of the flexible AC transmission system [ 3 ] [ 4 ] device family, regulating voltage, power factor, harmonics and stabilizing the system.

  5. Four-wire circuit - Wikipedia

    en.wikipedia.org/wiki/Four-wire_circuit

    As the public switched telephone network expanded in size and scope, using many individual wires inside the telco plant became so impractical and labor-intensive that in-office and inter-office signal wiring progressed to high bandwidth coaxial cable (still a popular interconnection method in the 21st century, used with the Lucent 5ESS Class-5 ...

  6. Static synchronous compensator - Wikipedia

    en.wikipedia.org/wiki/Static_synchronous_compensator

    Fundamentally, a STATCOM is type of static VAR compensator (SVC), with the main difference being that a STATCOM is a voltage-sourced converter while a traditional SVC is a current-sourced converter. Historically, STATCOM have been costlier than an SVC, in part due to higher cost of IGBTs), but in recent years IGBT power ratings have increased ...

  7. Single-line diagram - Wikipedia

    en.wikipedia.org/wiki/Single-line_diagram

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

  8. Four-terminal sensing - Wikipedia

    en.wikipedia.org/wiki/Four-terminal_sensing

    Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

  9. Ohmic contact - Wikipedia

    en.wikipedia.org/wiki/Ohmic_contact

    An ohmic contact is a non-rectifying electrical junction: a junction between two conductors that has a linear current–voltage (I–V) curve as with Ohm's law.Low-resistance ohmic contacts are used to allow charge to flow easily in both directions between the two conductors, without blocking due to rectification or excess power dissipation due to voltage thresholds.
