Functions of 3 phase isolation transformer

2023 04/20

Functions of isolation transformer:

1. Electrical safety isolation

2. Equipped with filtering and anti-interference function

3. It can effectively suppress the interference caused by high-order harmonics and lightning electromagnetic pulses introduced from the power line on the system

4. It can effectively suppress the interference of higher-order harmonics emitted by the electronic equipment of this system into the power distribution network and other equipment (devices and systems).

5. It can fundamentally prevent system malfunctions, data loss or errors caused by ground potential disturbances.

6. It can effectively prevent the hardware equipment in the system from being struck back and destroyed due to the sharp increase in the potential of the steel bars used as reference ground when the lightning protection device of the building is connected to lightning.

7. The reason why isolation transformer is widely used in construction is that the secondary of isolation transformer is not connected to the earth, and there is no potential difference between any two lines of the transformer and the earth. So it's safer. Isolation transformer is often used on electronic instruments with electronic tubes and high working voltage, such as electronic tube loudspeakers, oscilloscopes, etc., and can also be used for power maintenance.

8. Overcoming center point drift and improving power supply imbalance.

9. Anti surge impact and filtering function.
