The Advantages of an Isolation Transformer

Engineers often use an isolation transformer to maintain equipment separation from a power source. As a result, users are able to keep sensitive items like healthcare and laboratory equipment powered and protected. Due to the effective design, there are four main advantages that come with using an isolation transformer.


Perhaps the biggest advantage that isolation transformers offer is improved safety. This is particularly important in a setting such as a hospital or nursing home where expensive, life-supporting equipment has the potential for getting damaged. Using an isolation transformer also reduces the potential for doctors and patients to experience electrical shock as the result of defective equipment.

Reduces Surges

Another advantage of isolation transformers is that they reduce power surges. Electrical equipment can run smoothly without the risk of power surges because the DC signals from a power source are isolated. This means that equipment can function at a high level even if there is a power malfunction.

Noise Reduction

Another reason why isolation transformers are efficient is because of their noise reducing capabilities. The design of these devices naturally filters noise from power lines by using what are called separate Faraday shields. These shields help to block electric fields from interrupting the power flow. In turn, there is less electromagnetic noise involved with running electrical equipment.

Better Power Quality

There is usually better overall power quality when users employ an isolation transformer. The Faraday shields also help with efficiency because they reduce the potential for current leakage. As a result, important electrical devices can function at an optimized level.
