There are different types of transformers depending on your need. In this article, we are looking at isolation transformers and how they work. Generally, transformers are used to convert AC voltage from one level to a different level through electromagnetic induction. Depending on what the transformer is used for, the primary and secondary winding will differ.

You may have heard of step down or step up transformers. In a step down transformer, there is more primary winding compared to secondary winding. The reverse occurs when it comes to step up transformers. In an isolation transformer, there is isolation between the windings so that more safety is guaranteed for the people and appliances working with the transformer. This galvanic isolation stays in between the primary and secondary windings. You can have both step down or step up transformers in this category of isolation transformers. The main reason for selecting this type of a transformer is the improved safety. When the windings are not isolated from each other, there can be damage to appliances connected to transformer output when there is a fault in the transformer. And this will cause the client to replace all of the appliances. Another danger is that there is an increased possibility of electrical shocks for people. This is an all-around safe option.There is a huge peace of mind when it comes to using isolation transformers and you don’t need to worry about increased risk in the workplace. 

The isolation separates the devices powered by transformer power from its source. So there will not be any direct current flow. If you have expensive appliances, this is the right type of transformer to purchase. For example, many medical equipment are powered by isolation transformers. You will notice that the electronic devices tend to operate more smoothly as there is a definite reduction of power surges. This contributes to optimum performance of devices and machinery that are connected to transformer power. You can enjoy reduced noise when using isolation transformers as they use Faraday shields. This allows the transformer to avoid or filter certain electrical fields that can cause a disruption to the power flow. The output current produced by isolation transformers has reduced electromagnetic disturbances.

Another benefit of Faraday shields is that they will decrease the risk of current leakage. So you are receiving better quality power compared to what you will get with a different type of transformer. This contributes to efficiency of devices connected to transformer power. You can use these transformers in so many types of applications which gives them high versatility. You can use this power for telephone lines, pulse circuits and elevated potential devices. As mentioned above, medical equipment is powered by isolation transformers. This is because these equipment need high quality power for their complex circuitry. And a higher level of safety is required for devices used in public areas such as hospitals. It is easier to carry out testing and servicing of live circuitry, otherwise, there is a high chance of electrical shocks. Therefore, isolation transformers can make it safer for those involved in testing live circuitry.
