50/60Hz UPS Isolation Transformer 300KVA Three Phase Copper
Features
The establishment of a new neutral line-grounding in the photovoltaic isolation transformer can relieve the common mode interference and other neutral lines in the grid. The isolation transformer converts the three-wire delta connection into a four-wire Yo system, and shielding further eliminates the high frequency pulses coupled by the transformer. Interference and noise, although the shielded isolation transformer can effectively prevent the interference (pulse and high-frequency noise) from various NGs, the transformer must be properly grounded and very strict, otherwise the anti-common mode interference will be ineffective.
