Isolation transformers transfer electrical power from an electrical source of alternating power to an electronic device. In 2019, according to Consumer Reports, the electronics market earned about $301 billion. In almost every type of large electric equipment repair, you will find isolation transformers being used in the process. What else do you need to know about isolation transformers? Keep reading to find out.
They Enhance Safety
Isolation transformers allow devices that don’t have ground potential to be powered. They also allow service technicians to avoid electrical hazards when working on electrical devices. Without these types of transformers, the risk of electrocution would be much greater. They cut off the electrical supply so that components of the electronic device can be repaired without a shock hazard. Transformers unite the device to a power source without the potential hazards that can exist without the transformer in place. It separates the electric current.
They Only Protect One Device at a Time
Isolation transformers should only be used to protect one device at a time to ensure that all safety benefits are realized. These transformers offer a 1:1 ratio of protection. Misusing these transformers by connecting to more than one device can end badly. There are some that do have a 1:2 ratio but it’s best to do your research and know what equipment you’re working with before beginning your work.
They Rely on Galvanic Isolation
Galvanic isolation is a principle that is used in the design of isolation transformers. Galvanic isolation isolates sections of the electrical system so the current path is cut off. These transformers block the current of the DC component. However, there are other ways that can be used to send messages. For example, the transformer will block DC signals but it will allow AC signals to pass through.
It Is Used To Provide Power To Sensitive Equipment
This type of transformer, when installed with an electrostatic shield, can be used to power up sensitive equipment. The transformer helps to reduce interference and other noise that can affect the performance of sensitive electrical equipment. While there is no voltage regulation with these isolation transformers, and the noise is not necessarily mitigated, it is still just a physical hum.
There is a lot to learn about these transformers. They can provide a high degree of safety in the field and in the workshop. They also deliver benefits that are hard to find with other types of transformers. Call Bridgeport Magnetics today to learn more about the benefits these transformers offer.
