How Power Transformers Are Used In The Industries?

Power transformers are essential for providing electrical power to various parts of our society. They are used in hospitals, factories, and other commercial establishments. Additionally, power transformers are also used in transportation systems.

What is Power Transformer?

A power transformer is an electric machine that transforms the alternating current (AC) from a primary supply into a higher voltage, lower current form suitable for distribution. Transformers are used in industries such as electricity generation and transmission, telecommunications, aerospace engineering, renewable energy production, and industrial control.

To understand how power transformers are used in industry, it is important to first understand the different types of AC that exist. There are three basic types of AC: sinusoidal AC (a sine-waveform), square wave AC (a regularly repeating pattern of electrical pulses), and triphasic AC (three phases). 

Power transformers are generally categorized by the type of AC they convert. For example, a power transformer that converts sinusoidal AC into rectangular waveforms is called a rectifier. A power transformer that converts square wave AC into either DC or Alternating Current (AC) is called a switch-mode converter.

Types of Power Transformers

Transformers are machines that use electrical energy to change one type of energy into another. Transformers come in many different shapes and sizes. They are used in industries all around the world to power devices such as lights, motors, and electronics. 

There are three main types of power transformers: primary, secondary, and tertiary. Primary transformers take direct current (DC) electricity and turn it into alternating current (AC). Secondary transformers take AC and turn it into DC. Tertiary transformers take both AC and DC electricity and mix them so that they can be used more easily. 

There are many different types of electrical transformers available on the market today. Some of the most popular include micro transformers, which are used in small devices like cell phones; switch-mode transistors (SMT), which are used in larger industrial applications; oil-cooled transistors (OTMs), which have a high degree of efficiency; lead-acid batteries, which are often used for start engines; and GaN metal-oxide-semiconductor field-effect transistors (MOSFETs), which are becoming increasingly popular due to their low operating temperature.

Applications of Power Transformers in Industries

Industry uses substation power transformers in a broad range of applications. Some common uses include residential and commercial electrical wiring, powering industrial machines and appliances, providing backup power to critical infrastructure, and distributing electricity to rural villages. Power Transformers come in a variety of shapes and sizes for specific needs. They are also durable and efficient, ensuring reliability when needed most.

Cost and Benefits of Power Transformer

A power transformer is a device that transforms the alternating current (AC) or direct current (DC) into usable voltages. Transformers are used to convert the voltage of an electric supply to a different voltage and type of current required by appliances. In industrial settings, transformers are also used to step up or step down the voltage of a distribution line. Additionally, power Transformers can act as interconnectors between local sources of electricity and larger ‘utilities’ grids. 

The benefits of using power Transformers include increased throughput and efficiency for facilities consuming large amounts of electricity, shorter circuit lengths allowing for more installed capacity in a given area, improved protection against outages, reduced environmental impact due to lessened power consumption in electric-powered equipment, etc. The costs associated with power transformation depend on the specific application – e.g., the number and size of transformers required, installation costs, regulatory requirements, etc.


In today’s modern world, many different industries use power transformers. For example, in the automotive industry, power transformers are used to turn the high-voltage battery power of an electric car into low voltage for the electrical systems in the car. In the telecoms and IT sectors, power transformers are also used to convert high voltage from one system to another.
