2. John Dixon Gibbs - Wikipedia

   en.wikipedia.org/wiki/John_Dixon_Gibbs

   John Dixon Gibbs (1834–1912) was a British engineer and financier who, together with Lucien Gaulard, is often credited as the co-inventor of the AC step-down transformer. The transformer was first demonstrated in 1883 at London 's Royal Aquarium . [ 1 ]

3. Constant-voltage speaker system - Wikipedia

   en.wikipedia.org/wiki/Constant-voltage_speaker...

   Transformers with various taps allow the installer to adjust the sound pressure level up or down at an individual loudspeaker. Purpose-built models are available that have the transformer contained within the loudspeaker enclosure. The loudspeaker step-down transformer primary is connected in parallel to the constant-voltage line. [3]

4. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   These buildings have customer-owned transformers in the basement for step-down purposes. [5] Distribution transformers are also found in wind farm power collection networks, where they step up power from each wind turbine to connect to a substation that may be several miles (kilometers) distant. [6]

   AI startups and data centers desperately need step-down transformers to be able to plug into the grid and access electrical power. And solar and wind farms need step-up transformers to be able to ...

6. Transformer types - Wikipedia

   en.wikipedia.org/wiki/Transformer_types

   A transformer steps up the output of the system's amplifier to the distribution voltage. At the distant loudspeaker locations, a step-down transformer matches the speaker to the rated voltage of the line, so the speaker produces rated nominal output when the line is at nominal voltage.

7. Autotransformer - Wikipedia

   en.wikipedia.org/wiki/Autotransformer

   In a step-down transformer the source is usually connected across the entire winding while the load is connected by a tap across only a portion of the winding. In a step-up transformer, conversely, the load is attached across the full winding while the source is connected to a tap across a portion of the winding.
