What is a SG-80KVA three-phase isolation transformer？

3 phase isolation transformers are 3 phase transformers with isolated primary and secondary windings. As a result, the power input will be separated from the power output. It can safeguard sensitive equipment.

The feature of SG-80KVA three-phase isolation transformer

Establishing a new neutral-grounding in the isolation transformer can relieve the common mode interference and other neutrals in the power grid.
The isolation transformer converts the three-wire △ wiring into a four-wire Yo system,
and the shielding further eliminates the high-frequency pulse interference coupled by the transformer and noise.
