2. Voltage transformer - Wikipedia

   en.wikipedia.org/wiki/Voltage_transformer

   A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer

3. Buck–boost transformer - Wikipedia

   en.wikipedia.org/wiki/Buck–boost_transformer

   Buck–boost transformers can be used to power low voltage circuits including control, lighting circuits, or applications that require 12, 16, 24, 32 or 48 volts, consistent with the design's secondaries. The transformer is connected as an isolating transformer and the nameplate kVA rating is the transformer’s capacity. [2]

4. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   Most modern electronic devices require between 1.5 and 24 volts DC; lower-powered devices at these voltages can often work either from batteries or mains. Some devices incorporate a power supply and are simply plugged into the mains. Others use an external power supply comprising either a transformer and rectifier, or electronic circuitry.

5. Transformer - Wikipedia

   en.wikipedia.org/wiki/Transformer

   The transformer winding voltage ratio is equal to the winding turns ratio. [6] An ideal transformer is a reasonable approximation for a typical commercial transformer, with voltage ratio and winding turns ratio both being inversely proportional to the corresponding current ratio.

6. 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.

7. Transformer types - Wikipedia

   For example, an auto transformer that adapts a 1000 VA load rated at 120 volts to a 240 volt supply has an equivalent rating of at least: 1,000 VA (240 V – 120 V) / 240 V = 500 VA. However, the actual rating (shown on the tally plate) must be at least 1000 VA.
