Understanding Isolation Transformers

Isolation transformers block transmission between the primary and secondary electrical circuits. They play a vital role in protecting the power supply and electrical systems, allowing the voltage to increase from one section to another.

An isolation transformer is critical for many electrical systems and equipment.

How Does an Isolation Transformer Work?

An isolation transformer is connected between the power supply (input) and an electrical circuit or device (output) to prevent electrical currents from traveling directly between circuits. This isolation reduces the risk of equipment damage and protects people from electric shock.

Isolation transformers are designed to separate (isolate) a circuit from the supply. Typically isolation transformers provide the same voltage at the output as the input, however, voltage conversion is also possible and common if needed. Their primary function is to achieve circuit separation by isolating the primary and secondary windings, enhancing safety, and reducing electrical noise.

Many isolation transformers also include an electrostatic shield between the windings, which helps to block high-frequency noise from passing through to the output, offering additional protection for sensitive equipment.

Why Use Isolation Transformers?

Isolation transformers are essential for reducing common-mode and differential noise in electrical systems, often caused by outside interference or system imbalances. By isolating the primary and secondary windings, these transformers help prevent electrical noise from distorting sensitive equipment.

Additionally, isolation transformers can include electrostatic shields between windings, which block high-frequency noise and reduce ground loop interference. This feature enhances system reliability, especially in applications with sensitive electronics.

Choosing the Right Commercial Isolation Transformer

When selecting an isolation transformer, ensure it meets the specific voltage, current, and power requirements of your application. The right transformer provides effective isolation and protection, tailored to the operational demands of your system.
