2. Pad-mounted transformer - Wikipedia

   en.wikipedia.org/wiki/Pad-mounted_transformer

   Pad-mounted transformers are made in power ratings from around 15 to around 5000 kVA and often include built-in fuses and switches. Primary power cables may be connected with elbow connectors, which can be operated when energized using a hot stick and allows for flexibility in repair and maintenance.

3. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   Set sizes range from 8 to 30-kW (also 8 to 30-kVA single phase) for homes, small shops, and offices, with the larger industrial generators from 8-kW (11 kVA) up to 2,000-kW (2,500-kVA three phase) used for office complexes, factories, and other industrial facilities. A 2,000-kW set can be housed in a 40 ft (12 m) ISO container with a fuel tank ...

4. Transformer types - Wikipedia

   en.wikipedia.org/wiki/Transformer_types

   A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to ...

5. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   Transformers step down transmission voltages, 35 kV or more, down to primary distribution voltages. These are medium voltage circuits, usually 600–35 000 V. [1] From the transformer, power goes to the busbar that can split the distribution power off in multiple directions. The bus distributes power to distribution lines, which fan out to ...

6. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   Pole-mounted transformers may have lugs allowing direct mounting to a pole or may be mounted on cross-arms bolted to the pole. Aerial transformers, larger than around 75 kVA, may be mounted on a platform supported by one or more poles. [13] A three-phase service may use three identical transformers, one per phase.

7. Electric power transmission - Wikipedia

   en.wikipedia.org/wiki/Electric_power_transmission

   Voltage was stepped down to 100 volts using the Stanley transformer to power incandescent lamps at 23 businesses over 4,000 feet (1,200 m). [12] This practical demonstration of a transformer and alternating current lighting system led Westinghouse to begin installing AC systems later that year. [11] In 1888 the first designs for an AC motor ...
