  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

    In electronics testing and servicing, an isolation transformer is a 1:1 (under load) power transformer used for safety. Without it, exposed live metal in a device under test is at a hazardous voltage relative to grounded objects such as a heating radiator or oscilloscope ground lead (a particular hazard with some old vacuum-tube equipment with ...

  4. Ground loop (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_loop_(electricity)

    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. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    On the three secondary terminals, the center tap is grounded with a short strap to the transformer case. 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 ...

  6. Forward converter - Wikipedia

    en.wikipedia.org/wiki/Forward_converter

    A schematic showing the most important components of a forward converter. ATX PC Power Supply with Forward Converter (heat sinks are removed for better view) The forward converter is a DC/DC converter that uses a transformer to increase or decrease the output voltage (depending on the transformer ratio) and provide galvanic isolation for the ...

  7. Voltage transformer - Wikipedia

    en.wikipedia.org/wiki/Voltage_transformer

    A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer

  8. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    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. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  9. Galvanic isolation - Wikipedia

    en.wikipedia.org/wiki/Galvanic_isolation

    A transformer is the most widespread example of galvanic isolation. An opto-isolator is a very popular method of isolation in digital circuits. Cross-section of dual in-line package opto-isolators. Relative sizes of LED (red) and sensor (green) are exaggerated.
