How Do Step Down Transformers Work?

by Jeewan Garg Digital Marketing Company in India

The criss-crossing and wiggling power lines across the country carry electricity at enormously high voltages from power plants to our homes. These extremely voltage power lines have the capacity of exploding our regular appliances if we attach them directly to these electrical lines. Therefore there must be a way to reduce this high voltage electricity supply from power plants to the lower voltage electricity in our offices and homes. Also the standard voltage and frequency of alternating current (AC) used in homes is not the same in every country. For example, the voltages supplied in Indian homes are 220 volts, alternating at 50 cycles (Hertz) per second. But it is different in the United States- where they have 110-120 volts electricity with 60 cycles (Hertz) per second. The equipment that does this humming with the electromagnetic energy is the transformer.

A transformer is a static device with no moving parts. It functions transforming electrical power from one circuit to another with changes in current and voltage but no changes in frequency. The best step down transformer manufacturer in India suggests that Transformers are generally of two types which are classified according to their functioning:

  • Step Up Transformers

  • Step Down Transformers

Step Up Transformers convert low primary voltage to high secondary voltage- it steps up the input voltage.

Step Down Transformers are the complete opposite of step up transformers, as they convert high primary voltage to low secondary voltage.

Step Down Transformer

This is a transformer in which the output i.e. the secondary voltage is less than the input (primary) voltage is referred to as step-down transformer. A step down according to a step down manufacturer in India is a device that can be connected to the switch as well as the appliance.

How does it Work?

Although the working of the step down transformer depends on the way it has been designed and the number of windings they have on the primary and secondary, there is some insight the best step down transformer manufacturer in India would like to share with you:

The concept of step down transformer is very simple. The transformer is designed to have more turns on the wire of the primary coil in comparison to the number of turns on secondary coil. Therefore, if the second coil has as many coils as the primary coil, the secondary voltage will be half the size of the primary voltage. In general it implies that:-

Secondary Voltage ÷ Primary Voltage = Number of turns in secondary coil ÷ Number of turns in primary coil

Thus from the above finding we conclude that the formula used for developing the step down transformer is Vp/Vs=Np/Ns

Vp – Voltage on the primary

Vs – Voltage on the secondary

Np – Number of turns on the primary

Ns – Number of turns on the secondary

With these specifications and an amazing quality the best step down transformer manufacturer in India, Servo Stabilizers has created a name in the market for their step down transformers and are continuously satisfying their customers.
