A step-down transformer has more winding in the primary coil than secondary winding, reducing the voltage in the second terminal. The place we need reducing AC supply, we step down transformer there.
The transformer uses both electrical and electronic works. A step-down transformer use can be done in both electrical and electronic circuits. In this article, we will know about the uses of a step-down transformer.
Uses Of Step Down Transformer
The step-down transformer reduces electrical AC supply with the unchanged power and frequency in the output or supply terminal. To distribute electricity to commercial and residential connections, we need to reduce the transmission voltage from 220Kv to 220-440 volts.
Step down transformer is the only option we have to do this. Step Down transformer use is electrical and electronic circuit is given here below:
Step Down Transformer Use In Electrical Circuit
After generating the power, it is necessary to increase the voltage, which is transmitted at high voltages, e.g., 220kv, 400kv, 800kv, etc. But in residential or any commercial connection, we need 220/440 volts.
So, at the receiving end, voltages have to be reduced to 11kv / 6.6kv / 3.3kv for HT customers and 440 volts/ 220 volts for LT customers. In these circumstances, naturally, it requires a step-down transformer.
Step Down Transformer Use in Electronic Circuit
A step-down transformer works most likely to an adapter. The adapter reduces the voltage and also transforms the AC supply to DC. In the electronic circuit where we need AC supply, we use step down transformer there.
Like charging circuits, macing high impedance output from a solid-state or tube amplifier to a low impedance speaker or headphones, and various safety devices, and so on.
Where to use Step Down Transformer
So, a step-down transformer is being used:
- For reducing a high voltage AC supply to a lower output voltage to the user in electricity distribution.
- For providing a high current at a lower voltage, for example, to use for welding.
- For matching a high impedance output from a solid-state or tube amplifier to a low impedance speaker or headphones.
- For providing – for safety – isolation of your lower voltage ac supply from the mains power supply.
In the present world, electricity is the main element of every nation’s social and commercial development. For getting more accurate output in both electricity transmission and distribution, transformers are virtual devices.
