Where Are Auto Transformers Commonly Found?

 


Auto transformers utilize a single continuous winding with taps. It does not use two individual coils like traditional transformers. This not only increases efficiency in adjusting voltages but also reduces size.

Thanks to their ability to step up or step down AC voltage, these transformers can be used for voltage adjustments ranging from 40% to 110% of the input voltage.

From controlling motor speed and balancing electrical loads to improving operational efficiency, auto transformers are used for various applications.

In this blog, we explore the main spaces where auto transformers are indispensable.

Primary Applications of Auto Transformers

Industrial Environments With AC and DC motors

You will most commonly find auto transformers in industrial areas with AC and DC motors. The AC motor does not rely on the applied voltage to run at a high speed. So, to fulfill the need for a larger torque, industries use auto transformers to apply higher initiating voltages to get motors turning. Then, the voltage is reduced and a variable frequency drive is utilized to maintain the speed of the AC motor.

Substations

Another space is substations where the use of auto transformers is common. They are primarily used to maintain the higher efficiency of the substation. They enable safe and efficient power distribution from substations to different areas of a network. They balance power distribution by adjusting voltage levels.

Railway Systems

In railway systems as well, it is important to balance power distribution and maintain a continuous power supply to prevent severe damage to electrical systems. Again, auto transformers are used for their ability to fine-tune output voltages.

Additionally, in areas where routing new power lines is not feasible, these transformers are used to apply high voltages on the track rails over long distances. This simple boost in voltage helps increase the efficiency of existing lines.

Laboratory Equipment and Testing Stations

Last but not least, auto transformers are also found in laboratory equipment and testing stations.

With their ability to produce a variable output voltage and their high precision and accuracy, auto transformers make an ideal choice for use in scientific applications.

In testing stations, they are used to simulate different power scenarios. This helps ensure testing equipment operates optimally in all possible scenarios.

What is an Inverter Duty Transformer?

Image
  Inverter duty transformers (IDT) can be understood as one type of power transformer only. They send electrical energy from the source to the destination without altering frequency, making them useful in applications which require maintaining the same frequency. Technically, the inverter duty transformers are designed to step up or step down the voltage levels depending on the specific application requirement. It is mainly used in power distribution systems to step up or step down power voltage and transmitted over long distances. So, how do these transformers work? How Do Inverter Duty Transformers Work? Inverters convert direct current (DC) to alternating current (AC) at a lower voltage from sources such as solar panels; the inverter transformer steps up this voltage level to a higher value that is compatible with the electrical appliances to run. Once the inverter generates the AC output, it is directed into the primary winding of the inverter-duty transformer. Then, the AC fl...

India’s Rise in the Global Transformer Market

Image
  The manufacturing sector in India has been witnessing exponential growth in recent years. Various industries such as electronics, automobiles, aerospace, and medical devices play a significant role in industrial diversification and the country’s economic growth. Back in the days only a few countries like China, Germany, and the United States dominated the transformer manufacturing industry. India would rely on these nations for transformers and had a small export footprint in the global market. However, this over reliance on foreign players is significantly reduced and India is exporting transformers more than ever today. All thanks to government initiatives like "Make in India" and the rising domestic demand for power infrastructure, India has been able to increase its global market share and export value. Trust in India's Transformer Sector Grows Transformers enable safe and seamless transfer and distribution of power at appropriate voltage levels to residences and in...
