  2. File:Ground loop solution - isolation transformer.svg - Wikipedia

    en.wikipedia.org/wiki/File:Ground_loop_solution...

    English: A schematic diagram showing one solution to the problem of a ground loop between electronic components - insert an isolation transformer in the signal cable. A ground loop is an inadvertent electrical circuit or loop created by the ground wiring of electrical equipment. Ground loops are a major cause of hum and interference in audio ...

  3. Isolation transformer - Wikipedia

    en.wikipedia.org/wiki/Isolation_transformer

    An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons or to reduce transients and harmonics. [1] Isolation transformers provide galvanic isolation; no conductive ...

    Isolation transformer Use a ground loop isolation transformer in the cable. [4] [5] This is considered the best solution, as it breaks the DC connection between components while passing the differential signal on the line. Even if one or both components are ungrounded, no noise will be introduced.

  5. Sheath current filter - Wikipedia

    en.wikipedia.org/wiki/Sheath_current_filter

    Isolation transformers are transformers for low frequency analog and digital audio connections or rarely for high-frequencies in antenna cables between TV outlets and devices (tuner, VCR, TV, etc.). This filter then suppresses low-frequency ground loop currents on the sheath and core of coaxial cables, which can result from multiple grounds at ...

    en.wikipedia.org/wiki/Isolated-phase_bus

    In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant. Isolated phase bus during installation at the Bui Dam Ghana ...

    en.wikipedia.org/wiki/Single-wire_earth_return

    Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire ) to act as a ...

  9. Voltage transformer - Wikipedia

    en.wikipedia.org/wiki/Voltage_transformer

    Transformer winding primary (usually high-voltage) connecting wires are of many types. They may be labeled as H 1, H 2 (sometimes H 0 if it is internally designed to be grounded) and X 1, X2 and sometimes an X 3 tap may be present. Sometimes a second isolated winding (Y 1, Y 2, Y 3) (and third (Z 1, Z 2, Z 3) may also be available on the same ...
