High & Low Voltage Transformers – The Advantages


Electrical power transformers are crucial devices that are important for all kinds of commercial, industrial, and residential applications that require power transmission. But, do you need high voltage or low voltage transformers?

What are high voltage transformers?

High voltage transformers are used in industrial applications, those that are not directly used by end users. These transformers can handle electrical energy in the range of 23000 to 35000 volts. Because these voltages have to be transmitted across long distances, a high voltage transformer has a different core geometry, different winding methods, and different insulation methods, as compared to low voltage transformers. The main purposes of a high voltage transformer include electrical isolation, instrumentation, and power distribution and control. The most common applications include medical equipment, CRT displays, amplifiers, industrial measurement devices, power distribution control, and telephone networks. They are also used in high voltage labs for testing purposes.

What are low voltage transformers?

Low voltage transformers are those that are used at the consumer end of the energy grid, where they maintain the electrical environment safe in both commercial and residential buildings by stepping down the voltage to a safer value. Low voltage transformers have their primary and secondary windings designed to operate at system voltages in the low voltage class. The power supply of a low voltage transformer ranges between 12 to 24 volts, which does not typically generate heat. Low voltage transformers take the high voltage electricity of 120 volts running through the walls of the home, and step it down to 12 or 24 volts, so that the electricity can safely run through the fixtures, thus reducing the chances of shocks and providing protection against short circuits. The units have timers that can be set for up to 8 hours. These low voltages are so safe that one can install a light bulb even when the power is on. Low voltage transformers are small in size and have a variety of mounting configurations. The main applications that use low voltage transformers include thermostats, street lights, door bells, and under-counter lightings.

We can see how both high and low voltage transformers are useful in their own ways. With the high voltage transformers being used in industrial applications, and low voltage transformers being used in residential applications, we can say that both high voltage and low voltage transformers are important for our daily lives. Together, they work to provide uninterrupted power to our homes and offices. Hence, none of the two is better than the other. Each one has its own advantages. However, you must be able to choose the right one, depending on your requirements.
