Any electrically powered building or piece of equipment can receive energy from an AC grid power supply through the use of a transformer. For safety reasons, isolation transformers are typically needed in these applications to electrically isolate the powered equipment from the power source. The equipment and electronics are kept secure by the electrical isolation, which also helps to lower electrical noise. This is the reason why isolation transformers are employed in numerous electrical and electronic applications. This blog examines the value of and advantages of isolation transformers.
How important are isolation transformers?
Isolation transformers use magnetic flux to connect the main and secondary. By doing this, the circuit connected to the primary is electrically separated from the circuit connected to the secondary. Even in the most sensitive instruments, this separation helps limit introduced noise. These types of transformers are used in numerous applications, including power supplies for delicate equipment, industrial devices, and medical equipment. These transformers often feature windings mounted on a single ferromagnetic core that creates a shared flux link connecting the primary and secondary. It is always safer to connect an electronic equipment to an isolation transformer rather than to the power grid.
Advantages of using an isolation transformer
The main advantage of an isolation transformer is safety, as we’ve already noted above. Other than that, there are many more advantages, which are as follows.
- Devices can be safeguarded against harm from electrical surges and external short circuits.
- Circuits can be divided by electrically disconnecting the primary and secondary windings.
- Electromagnetic interference can be eliminated in applications for sound and amplifiers.
- The radio frequency noise produced by the circuit’s high-power gadgets can be lessened.
- Power surges and fluctuations can be reduced when electrical equipment is isolated from the power source.
- Current leakage can be limited.
When to use an isolation transformer?
While isolation transformers can be used in a variety of applications, they are extremely helpful and useful in highly sensitive instruments, such as the medical industry. In such fields, the noise due to other devices on the same grid has a significant impact on the dependability of the sensors. Such equipment would operate more dependably if connected to an isolation transformer first, then to a UPS system. Additionally, it guarantees electrical shock safety, which is crucial in a medical setting. Medical equipment needs to be handled with extreme caution since even a small flaw could have disastrous results. For medical devices, isolation transformers offer the precision, dependability, and safety that are crucial.
