    A solar lamp in a private garden. There are many different types of landscape lighting systems, controls and switching, wiring connections, fixture types, functions-purposes-styles, and light sources. Components can include: Power connection to main property power source (code and permit determined) Transformers (12v and multi-tap transformers ...

  3. Pad-mounted transformer - Wikipedia

    en.wikipedia.org/wiki/Pad-mounted_transformer

    A padmount or pad-mounted transformer is a ground-mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure.

    Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US for residential customers. The power comes to the customer via a service drop and an electricity meter. The final circuit in an urban system may be less than 15 metres (50 ft) but may be ...

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

  7. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    Resonant transformers are also used in electronic ballasts for gas discharge lamps, and high voltage power supplies. They are also used in some types of switching power supplies. [6] Here the short-circuit inductance value is an important parameter that determines the resonance frequency of the resonant transformer. Often only secondary winding ...
