How Are Power Transformers Growing Important?


Can you imagine life without electricity today? The answer is ‘No’. Electricity and Energy have become the most important parts of our everyday life. All our appliances work on electricity – TV, home theatre systems, refrigerators, microwave ovens, and most importantly – our mobiles are charged because of electricity! But, along with electricity comes voltage and fluctuation problems, because of which our appliances tend to malfunction. This is where transformers help us! They change the alternating current from one circuit to another by electromagnetic induction to reduce or increase the voltage of electrical equipment as required.

How are power transformers useful?

Electrical power generated in a low voltage level is very cost effective. If the voltage level is increased, the power current is reduced which reduces the ohmic loss, cross-sectional area of the conductor and the capital cost of the system, while improving the voltage regulation. Thus, low level power must be stepped up for efficient electrical power transmission by a step-up transformer at the sending side of the power system network. Similarly, because high voltage cannot be distributed to the consumers directly, it must be stepped down at the receiving end by a step-down transformer. Where the ratio between high voltage and less voltage is less than 2, auto transformers are used; and where the ratio is greater than two, two-winding transformers are used.

How do power transformers play a role in the industry?

Power transformers have created a great difference in our lives and are used in several power operated systems available in the market today. With the increasing demand for electrically operated systems, the manufacture of power transformers in India is on the rise. Today, major industrial units are looking forward to increase the capacity of power transformers. Leading industries are coming up with better manufacturing ideas and innovative concepts, keeping in mind the modern business demands, and making sure that the electromagnetic requirements and compatibility factors are met with.

What are the electrical components used with a power transformer?

  • Electrical contacts are electrical components used to stop electricity flow by interrupting the current from one end to the other. They are available for high voltage, medium current and low current devices.
  • The circuit breaker is an electrical switch that automatically turns off or interrupts a circuit damage caused by high voltage. Unlike a fuse, circuit breakers can be reset manually or automatically to resume normal operation.
  • Ferrite Bead Coils are a chief component of an electronic device. They help reduce the intensity of noise that originates from electronic circuits.
