The Power of Transformers and Polyphase Transmission

For the most part, we do not stop to think about transformers and how they really make our lives so much easier. This is probably because they are easily overlooked when everything is working the way it should, but it becomes very apparent when one stops functioning properly. We usually consider a downed power line a hassle because it takes a couple hours to fix, but a broken transformer could take several days to repair. What are these often overlooked but extremely important devices?

Transformers are used to control the electrical power we use. One transformer is used to lower the voltage level of the electricity coming from power plants to a level that can be transported out along power lines, and another transformer is used to lower the voltage further to a level that is safe to be sent into homes and offices. Most of the devices we use have transformers that will alter the voltage of your wall socket even further to properly suit the specific electrical requirements of the device.

The transmission of power using transformers can be accomplished in several different ways, one of which is polyphase power transmission. The most common method of polyphase power transmission uses a 3 phase transformer. The electrical transmission capacity of the polyphase option far outshines single phase transmission, but it requires lower power levels from transmission wires. Three phase transformers make it possible to transfer this increased capacity to the locations where the power will be used, and they are also utilized for products and large industrial equipment that require 3 phase electricity.
