Find out the different applications of voltage transformers and how they work.

Selection of Voltage Transformers
Provides guidelines on how to size and select the right voltage transformer for the application. 

  High Voltage Transformers
These transformers are designed to handle large amounts of electricity, usually from 600 - 5,000v.
 

Medium Voltage Transformers
Offers the most load diversity and is offered in a wide range of configurations.

  Low Voltage Transformers
Used most frequency in lighting applications. Are designed to reduce 120 voltages down to 12 voltages.

Low Voltage Transformers

Low voltage transformers typical applications is for landscaping and for low lighting in homes and business. Low voltage transformers are designed to reduce 120 volt line voltage to a secondary, or output of 12 volts.

When using low voltage transformers remember the transformer has no way of knowing the line voltage It simple reduces the current by a factor of 10. If the line voltage was 130 volts the transformer would produce 13 volts. Line voltage may vary throughout the day, for this reason it is important to measure the line voltage at the transformer is to be used.

The voltage will also decrease the further it has to travel, to compensate for this and variations in line voltage they use multi-tap transformers. These transformers offer voltage outputs ranging from 10 volts to 14 volts. How they work is having leads coming off the primary or secondary coil at different point near the end of the coil to produce several different voltages. This gives better control over light output and lamp life.

Many use a buck boost transformers which can change the line voltage a small amount. Buck boost transformers can raise or lower the amount by about 10%. Some use these transformers to boost voltage on the secondary side. It is designed to be buried in the ground as part of the circuit. The typical boost is around 20 two 25%. If the voltage drop is down to 10 volts at the fixture, installing a buck boost transformer ahead of the fixture could increase it to 12 or more volts.

It is always important to remember that low voltage transformers can not stabilize voltage variations. They simply transfer the current at a fixed ratio and do not sense changes.

Low voltage transformers are offered with and without a cabinet. Those without are attached to a electrical box and wired directly to the line voltage source. Low voltage transformers should have UL listing for the intended use. It may be listed for indoor, outdoor or both. Listed products will have the UL symbol and be marked for the type of use along with a control number on the device.

Step-Down Transformers
It is defined as a transformer that reduces or step-down voltage.

  Step-Up Transformers
A step-up transformer is designed where the secondary voltage is greater than it's primary voltage and step-up the voltage.

   Distribution  Transformers
Are categorized in dry-type or liquid-immersed type, and available in single or three phase.
