The technical parameters of SG-80KVA three-phase isolation transformer

Transformer technical parameters: SG series three-phase dry-type isolation transformer is the factory's reference to international similar products, in line with IEC60076-11 and GB6450 and other international and national standards, the winding adopts the method of complete tire winding. Transformers are vacuum dipped to achieve transformer insulation class H and product performance to international advanced levels.

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, although the shielded isolation transformer can effectively prevent interference (pulse and high frequency noise) from various NG, the transformer must be properly grounded and very strict, otherwise the common mode interference will be ineffective.
