The Basic Function Of An Isolation Transformer

The Basic Function Of An Isolation Transformer

In some types of application or equipment, it is critical to avoid any type of shock and current to certain areas or component of the system. The need to protect from electrical shock may also be essential for people working in and around equipment.

In these types of applications, an isolation transformer may be the ideal option. They are installed in many different types of systems and equipment to address potential issues with faults occurring in the system which may be dangerous to people or create the risk of damage to sensitive electronic components and equipment.

The Basics

In a simple statement, the use of the isolation transformer is to allow the transfer of the electrical power between two circuits which, for safety reasons, cannot be directly connected. The AC power source is not directly connected to the powered device through the use of this specialized transformer.

In design, the isolation transformer typically has additional, significant isolation between the primary and secondary windings. In other transformers these windings are separate, but they are not usually insulated from each other. Additionally, these transformers are built with high voltage situations in mind, eliminating issues with strong electromagnetic fields and specialized cores, which may allow direct transmission through other types of transformers.

With the DC current blocked in these types of transformers, there is no risk of electronic shock. They can also be used to prevent interference which can occur with the development of a ground loop, which may also be known as an earth loop. These loops result in the noise, interference, and hum within a system, resulting in poor performance of all types of electronic equipment and systems.

There are many different types of transformers used for isolation. These components are typically custom made to meet the specific demands and requirements of the system. They can be standard shape and design or customized for unique application requirements.
