Choke Coil

The establishment of a new neutral line-grounding in the step-up isolation transformer can remove the common mode interference and other neutral lines in the power grid. The step-up isolation transformer converts the three-wire △ wiring into the four-wire Yo system, and the shielding can further eliminate the high-frequency pulse interference and noise coupled by the transformer. Although the shielded isolation transformer can effectively prevent various N-G interference (pulse and high-frequency noise), the transformer must be properly grounded, It is very strict, otherwise the anti-common-mode interference will have no effect. The company can design and produce high-quality isolation transformers for customers.
