Benefits of using isolation transformers:

Isolation transformers mainly have the following advantages:

  • Good safety: The biggest advantage offered by isolation transformers is increased safety. This is especially important in settings such as hospitals or nursing homes where expensive life support equipment can be damaged.
  • Reduce surges: Another advantage of isolation transformers is that they reduce surges. Since the DC signal from the power source is isolated, electrical equipment can run smoothly without the risk of power surges. This means that even in the event of a power failure, the device can function normally.
  • Low noise: The isolation transformer has the advantage of lower noise than ordinary transformers.
  • Better Power Quality: When a user uses an isolation transformer, there is usually a better overall power quality. Faraday shields also help improve efficiency because they reduce the likelihood of current leakage. As a result, important electrical equipment can operate at an optimized level.
