What is Electrical Transformer Electrical transformers are machines that transfer

electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about an increase in the voltage and vice versa.

Transformers help improve safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances.

Applications Of Transformer It can rise or lower the level of level of Voltage

or Current ( when voltage increases, current decreases and vice virsa because  P =V x I, and Power is same )  in an AC Circuit.

It can increase or decrease the value of capacitor, an inductor or resistance in an AC circuit. It can thus act as an impedance transferring device.  

It can be used to prevent DC from passing from one circuit to the other. 

Transformer is the main reason to transmit and distribute power in AC instead of DC, because Transformer not work on DC so there are too difficulties to transmit power in DC.

Types Of Electrical Transformers

Dry Type Transformer Distribution Transformer Cast Resin Transformer OLTC Transformer Power Transformer Air Cooled Transformer High Voltage Transformer Low Voltage Transformer

Dry Type Transformer Dry-type transformer is a completely stationary solid-state device and it needs less maintenance to provide problem-free service. This transformer doesn’t contain any moving parts. Not like liquid fill transformers, this transformer use simply high-temperature insulation systems as they are very safe environmentally.

Distribution TransformerA distribution transformer is also known as a typical kind of isolation transformer. The main function of this transformer is to alter the high voltage to the normal voltage like 240/120 V to use in electric power distribution. In the distribution system, there are different kinds of transformers available like single phase, 3-phase, underground, pad-mounted, pole-mounted transformer.

Low Voltage TransformerA low voltage transformer is at the heart of every landscape lighting system. It converts 120 volt current to a low voltage current The efficiency of this conversion determines how well the transformer controls voltage output and how much energy is consumed in the process. VOLT® transformers are the most efficient multi-tap low voltage transformers in the industry, providing high performance and energy savings.

High Voltage TransformerHt Transformers with built-in ht automatic voltage regulators provide total solutions for voltage regulation and stabilization. Most of the times, it has been realized that even after installing Distribution Transformers, the problem of fluctuating voltage remains on the lt side, resulting in improper function of Electrical Systems. The HT Transformer is basically a combination of HT avr.

Cast Resin TransformerCast resin transformer has another name that is Dry-type transformer. They are the type of distribution transformer not use liquid to cool the coil but by air.

Maybe you are searching for the advantages and disadvantages of cast resin dry-type transformers. You want to find complete information about their appliance to choose the right cast resin transformer for your factory.

OLTC TransformersAn electrical device which works on the principle of faraday’s law of induction is a transformer, where faraday’s law states that the magnitude of the emf produced inside a conductor is due to electromagnetic induction. A OLTC transformer consists of two types of windings like primary & secondary.

Power TransformerPower Transformers are static electrical machines, where one level of electrical energy that is lead to all primary equipment of the device is being transformed into second level electricity in all secondary windings. The electricity is with equal frequency but with a phase shift for a certain degree.

Air Cooled TransformerAir Cooled Transformer, the heat generated is conducted across the core and windings and is dissipated from the outer surface of the core and windings to the surrounding air.Air Natural (AN)This method uses the ambient air as the cooling medium. The natural circulation of the air is used for dissipation of heat generated by natural convection.
