A three-phase isolation transformer is a device used to introduce current from one power source to another load while protecting the load from potential electrical interference generated by other power equipment. It consists of three coils that are separated by insulation to avoid arc failures. The three-phase isolation transformer uses electromagnetic induction to transfer current from one coil to the other coil, and at the same time, these coils are isolated by insulation material, so that the transformer can effectively reduce noise, reduce harmonics and reduce loss.
The main roles of the three-phase isolation transformer include:
Electrical safety isolation: Provides electrical safety isolation to prevent electronic components from being impacted by excessive voltage or current.
Filter anti-interference function: with filter and anti-interference function, can effectively inhibit the introduction of high order harmonics and lightning electromagnetic pulse from the power line interference to the system.
Inhibit high order harmonics and lightning electromagnetic pulse: can effectively inhibit the high order harmonics issued by the electronic equipment of the system into the power distribution network to other equipment (devices and systems) interference.
Prevent system working disorder: fundamentally prevent system working disorder, data loss or error caused by ground potential disturbance.
Anti-surge impact and filtering function: with anti-surge impact and filtering function, improve the power supply imbalance.
Three-phase isolation transformers are widely used in many fields, such as industrial control systems, power plants, electronics and communication fields and transportation fields. In industrial control systems, it acts as a compensation device to protect the load from potential electrical interference generated by other electrical equipment. In power plants, it is used to deliver high voltage to low voltage areas or vice versa to meet the needs of different circuits. In the field of electronics and communications, it is used to protect electronic components from excessive voltage or current shock by isolating coils. In the field of transportation, it is used to control the speed of electric motors and the electromagnetic interference generated by electric motors
