Step Down Transformer

A step down transformer converts high-voltage, low-current power into low-voltage, high-current power.   They are designed with a high turn count of the primary winding and low turn count of the secondary.  In many cases you will see larger-gauge wire used in the secondary winding because of the increase in current.  The primary winding may be made of smaller-gauge wire because it doesn’t have to conduct as much current.

Understanding how a Step Down Transformer Works

A step down transformer is a electrical device and is constructed like most transformers that transform voltage through magnetic coupling.  A step down transformer has a magnetic core (usually made of iron) with one winding of wire placed close to one or more windings, which can couple two or more alternating current  (AC) circuits together by employing the induction between the windings.  The primary winding is connected to the power source, and the other windings are known as secondary.  When the secondary voltage is less than the primary, the device is known as a step down transformer.  If the secondary voltage is higher than the primary it is called a step up transformer.

Step Down Transformer Applications

Step down transformers are used extensively in our electric power systems.  In an electric power system, a step up transformer is used to raise voltage and decrease current to travel long distances over transmission wires.  These wires carry the electricity to sub-stations where a step down transformer is used to reduce the voltage, and increase the current.  These substations pass the lower voltage on and usually before it reaches its final destination, to our home and business, a step down transformer is again used to lower the voltage to 120-240V. Step down transformers are also found in many electronic devices, and used in a wide variety of industrial and commercial applications.  They are available in single phase and three phase and come in a wide array of sizes.  

Step-Down Transformer Efficiency

Step down transformers are simple devices which have no moving parts so they require minimal maintenance and have a long life.  Because of this it is wise to purchase a step down transformer that is efficient.  With the right material and design a step down transformer can have around 99% efficiency.  This can be obtained by a combination of transformer construction factors including using special steel alloys to couple the induced magnetic fields between the primary and secondary windings.  There are two main types of metal used in the winding of the step down transformer; one is aluminum and the other being copper.  Copper wiring dissipates less heat and is less corrosive than aluminum.  Less heat dissipation produces more efficiency in transformers because less electricity is last as heat.  Because of the durable nature of copper this type of transformer will also require less maintenance.  Step down transformers with copper wiring and special design initially cost more, but the saving on electrical cost over time more than makes up for the price.
