  2. Unimog - Wikipedia

    en.wikipedia.org/wiki/Unimog

    1948 Boehringer Unimog 70200 2018 Unimog 437.4 Firefighter. The Unimog (pronunciation in American English: YOU-nuh-mog; British English: YOU-knee-mog; [1] German: [ˈʊnɪmɔk], listen ⓘ) is a Daimler Truck line of multi-purpose, highly offroad capable AWD vehicles with Power take-off (PTO) driveshafts that since 1948 can be used with additional equipment in the roles of tractors, light ...

  3. Tap changer - Wikipedia

    en.wikipedia.org/wiki/Tap_changer

    Tap changer. Motor drive unit of a on-load tap-changer. A tap changer is a mechanism in transformers that allows for variable turn ratios to be selected in distinct steps. This is done by connecting to a number of access points, known as taps along either the primary or secondary windings. Tap changers exist in two primary types, [1] no-load ...

  4. Phase converter - Wikipedia

    en.wikipedia.org/wiki/Phase_converter

    An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.

  5. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    This style of transformer gives an extremely wide bandwidth but only a limited number of impedance ratios (such as 1:1, 1:4, or 1:9) can be achieved with this technique. Choke transformers are sometimes called transmission-line transformers (although see below for a different transformer type with the same name ), or Guanella transformers , or ...

  6. Autotransformer - Wikipedia

    en.wikipedia.org/wiki/Autotransformer

    An autotransformer has a single winding with two end terminals and one or more terminals at intermediate tap points. It is a transformer in which the primary and secondary coils have part of their turns in common. The portion of the winding shared by both the primary and secondary is the common section. The portion of the winding not shared by ...

  7. Dissolved gas analysis - Wikipedia

    en.wikipedia.org/wiki/Dissolved_gas_analysis

    Dissolved gas analysis (DGA) is an examination of electrical transformer oil contaminants. [1] Insulating materials within electrical equipment liberate gases as they slowly break down over time. The composition and distribution of these dissolved gases are indicators of the effects of deterioration, such as pyrolysis or partial discharge, and ...

  8. Myelin oligodendrocyte glycoprotein - Wikipedia

    en.wikipedia.org/wiki/Myelin_oligodendrocyte...

    Alternatively spliced human mRNA of the MOG gene form at least nine isoforms. [12] The crystal structure of myelin oligodendrocyte glycoprotein was determined by x-ray diffraction at a resolution of 1.45 Angstroms, using protein from the Norway rat. This protein is 139 residues long, and is a member of the immunoglobulin superfamily. [13]

  9. 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 ...
