Product Description

30KVA Low Voltage Three Phase Dry Type Transformer 230V 110V IP20



1. Feature


Establishing a new neutral-grounding in the transformer can relieve the common mode interference and other neutral problems in the power grid. The isolation transformer converts the three-wire delta connection into a four-wire Yo system, and shielding further eliminates the high-frequency pulse interference and internal coupling of the transformer. Noise, although the shielded isolation transformer can effectively prevent various NG interference (pulse and high-frequency noise), the transformer must be properly grounded and very strict, otherwise the anti-common mode interference will be ineffective. We can design and produce high-quality isolation transformers for customers.
