2. Pad-mounted transformer - Wikipedia

   en.wikipedia.org/wiki/Pad-mounted_transformer

   Pad-mount transformers operate on medium-voltage distribution systems, up to about 35 kV. The low-voltage winding matches the customer requirement and may be single-phase or three-phase. Pad-mount transformers are (nearly always) oil-filled units and so must be mounted outdoors only. The core and coils are enclosed in a steel oil-filled tank ...

3. Transformer types - Wikipedia

   en.wikipedia.org/wiki/Transformer_types

   For voltage ratios that don't exceed about 3:1, an autotransformer is cheaper, lighter, smaller, and more efficient than an isolating (two-winding) transformer of the same rating. [3] Large three-phase autotransformers are used in electric power distribution systems, for example, to interconnect 220 kV and 33 kV sub-transmission networks or ...

4. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...

5. Vector group - Wikipedia

   en.wikipedia.org/wiki/Vector_group

   The phase windings of a polyphase transformer can be connected internally in different configurations, depending on what characteristics are needed from the transformer. In a three-phase power system, it may be necessary to connect a three-wire system to a four-wire system, or vice versa.

6. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]
