One of the most difficult subjects to understand for many women and men is that of transformers. If someone is to ask me anything about a 480v transformer, I will just stare at him or her, which is exactly what happens. This is enough and today is the day in which we will all learn what these transformers are about and what they can do for us. Firstly, you need to know what a transformer is and what it can do. All over the world, you will find that they use these three phase transformers to change the different values of three phase currents and voltages.
The three phase transformers that you hear about is the most common way for them to use, transmit and produce power. The secret of this item lies in the way in which the different connections work to give you the electricity you need to run your daily lives.
It is very interesting to know exactly how they put this transformer together which ultimately makes it work. They take three single-phase transformers and wind them together to give you one core. Once this is over they seal it properly before they fill it with a substance they call dielectric oil.
Yes, I also thought that they are crazy for mixing a liquid with something through which electricity will run. The oil will not cause any damage and actually have a few functions to provide. Because it is dielectric oil, it is a non-conductor of electricity. This is the item, which will work as insulation between the casing and the different windings.
They use these 480v transformers to provide energy in four different ways. Firstly, you have your industrial area, which takes up a large amount of energy. In this case, the combination of transformers will be delta to delta. Secondly, for the more commercial but industrial sectors the delta to wye combination will work perfect.
In the third place, you have your transmissions with very high voltage readings, which will be a combination of wye to delta. The rarest combination of the four is the wye to wye. They are not likely to use this combination as it generally cause balance and harmonic problems.
Delta and Wye is just the way in which they connect the different wires of the transformers. Now that you know how they connect transformers and what you can use them for, you will feel better in a conversation with a few electricians.
