Know the Top Advantages of High and Low Voltage Transformers

Proper knowledge about different types of transformers is very essential for the entire working process in any kind of industry or company.

A transformer is a special kind of static and simple electro-magnetic passive electrical device, which is developed to convert the alternative type of current from one voltage to the other one when needed. It is also beneficial for “step up” or: step down” voltages and actually it works on the theory and rules of magnetic induction.

High voltage transformers are basically used in high the labs of high voltages for various types of testing purposes. These types of transformers are subjected to transient voltages and surges at the time of their regular operation when the insulation breaks down under a test. To withstand and prevent any damage, these impulse voltages, and also the insulation of  those types of transformers must be designed with great care. These types are basically single phase, core type transformers.

This type of transformers is actually oil immersed. Bakelite sheets are used for the purpose of separating the windings of high tension and low tension. The high voltages transformers are used for the work of HV cable testing always need the supply of sufficient current. This machine can generate a great amount of heat, and for this reason the cooling system of these types of transformers is designed with great care. To ensure proper transformer voltage regulation special care is also required. Many manufacturers of transformers create these types of transformers with utmost care.

One of the widely used customized transformers across a large number of industrial buildings is a special type of pulse transformer, which are planned and developed to carry high loads to distribute the power needed. They are efficient in transferring a large amount of power than a normal and regular transmitter of the same size and can easily work on high frequencies. Its high voltage resistance makes the high voltage transformers more powerful for the operation of a large scale. Some advantages of these types of high voltage transformers are:

1. Power to Transfer the High Energy: The main advantage to high voltage transformers is the efficiency to make the smaller components work more in amount. High energy can be transferred easily with a minimum rise-time and wide pulse-width in a good and powerful pulse transformer, which is nothing but a high voltage transformer. The high power of its ferrite core helps in managing and reducing the leakage inductance. Its high voltage resistance of these types of transformers makes it the best option for any type of large scale operations.
2. Windings which are more in number: With more than two windings, this high voltage transformer called the pulse transformer uses more than one transistor simultaneously. It helps in the problems of limit phase shifts. Less turns is another form of less resistance and more power.
3. Preventing the stray Currents: These high voltage transformers or Pulse transformers have galvanic isolation between the windings. These windings prevent the passing of stray currents while working. It also allows both the primary driving circuit and the secondary driven circuit to use different kinds of powers..
4. Provides good Insulation and Control: Abrasive resins in the structure of a high voltage pulse transformer help in controlling the electric resistance or any other vibrations generating inside the transformer. Those are the part of a procedure, which is known as vacuum potting. This comprises silicone rubber gel or thermo-setting plastics. The potting compound provides insulation thus providing better efficiency.

Now we can talk about the low voltage transformers and their advantages and efficiency.

The transformers, which are of low voltage, are used or operated by electrical loads. The service provider supplies power to their customers at a fixed voltage level, which is being accepted nationally. A transformer that can lower the supply voltage from the amount of 415V three phase or 240V single phase to any stage of lower value is called as the low voltage transformer. It is basically a kind of step-down transformer. This device is always needed at the time when, there are voltage discrepancies or differences between the power which is being supplied and the electrical device voltage rating. It’s very important to note that the devices which can easily work with low voltage are actually safer because we all know that the lower the voltage the less the dangers or results of faults. Many transformer manufacturers are capable of creating these low voltage transformers as well.

The low voltage transformers are those types of devices, which are used at the consumer end of the energy grid. In these cases they try to maintain the safe electrical environment in both industrial and residential buildings by stepping down the amount of the voltage to a value of a safer value. Low voltage transformers have their own primary and secondary windings, which are being created to operate at system voltages in the class of low voltages. The power supply of a low voltage transformer comes between 12 to 24 volts, which is basically not capable of generating a good amount of heat. Therefore the low voltage transformers help in a way that the electricity can safely run through the fixtures, and in this way they can reduce the chances of shocks and provides protection against dangers and harmful short circuits. These low voltages are very safe and one can easily install a light bulb while the power is on. Low voltage transformers come in small sizes and have a large variety and options of mounting configurations.

From the above points we can see how both the high and low voltage transformers are proved to be very useful in their own ways and working processes. As the high voltage transformers are good for industrial applications, on the other hand, the low voltage transformers are beneficial for the residential uses; we can say that both transformers are essential for our daily lives in their own ways. Together, they work to provide uninterrupted power to our homes and offices.

Many top transformer manufacturing companies are capable of designing and offering both types of transformers.
