Isolation transformers are essential devices used to transfer electrical power from a source of alternating current (AC) power to equipment or devices while providing electrical isolation between the source and the load. This isolation is crucial for safety reasons, as it protects against electric shock, suppresses electrical noise in sensitive devices, and prevents the transmission of electrical faults.

These transformers are designed with separate primary and secondary windings that are not electrically connected but are magnetically coupled. This design ensures that there is no direct electrical path between the input and output, effectively isolating the two circuits. Isolation transformers can also block the transmission of DC components while allowing AC components to pass through.

One of the key benefits of isolation transformers is their ability to reduce electromagnetic interference and voltage spikes, which can be particularly important for sensitive equipment such as medical devices, computers, and laboratory instruments. They are often equipped with features like high-temperature enameled wire, excellent insulating paper, and cooling fans to enhance performance and safety.

Isolation transformers are available in various configurations, including single-phase and three-phase models, with capacities ranging from a few kilovolt-amperes (kVA) to several hundred kVA. They can be customized to meet specific voltage requirements, winding configurations, and sizes, making them suitable for a wide range of applications.

In addition to their safety and noise reduction capabilities, isolation transformers can also improve the quality of electrical power by providing voltage regulation and reducing the risk of ground loops. They are commonly used in medical equipment, industrial control systems, and electronic testing environments where electrical isolation is critical.

Isolation transformers play a vital role in ensuring the safe and efficient operation of electrical systems by providing essential electrical isolation and protection against various electrical disturbances.
