Applications of Transformer 

The fundamental application of transformer includes

  1. Isolation Protection
  2. ⚡ Voltage Conversion as you normally encounter in distribution and power supply and
  3. Impedance Matching as employed for instance in amplification

Some people are confused when they encounter transformer with multiple leads whether they are troubleshooting or fabricating, and some of the reasons are they don’t know which one is primary or secondary: not only this some winding are out of phase with the other and if use as it is without consideration  and figuring it out, you get wrong output. You need to check phase arrangement of the coil before connecting to the rest of the circuit. There is usually mark to indicate this and you can confirm this if you have a circuit diagram to work with and for more information on transformer, CHECK OUT this video link. When you finish with the video you could send us a reply or questions on the topic for more detail understanding.

Transformer may experience a short or open circuit depending on the stress to which it was subjected. The pry side is more vulnerable if it is a step down transformer because it usually has more turns at high resistance especially if there is a surge and any problems from the secondary side will reflect on the primary.  To keep your transformer save, use a fuse before the primary and after the secondary and any of these fuse should never be bypass, some manufacturers equipped their transformer with thermal fuse in the primary; in this case when you observe an open in the pry coil look for this. It is cheaper to replace the thermal fuse than the entire transformer. For more on applications of transformers and projects CONTACT US.
