Tips: Characteristics of CCHN isolation transformer at the AC power input
- If the third harmonic and interference signal of the Grid is severe, use isolation transformer to remove the third harmonic and reduce the interference signal.
- The use of isolation transformers can generate a new neutral line to avoid the abnormal operation of equipment caused by unfit neutral power line.
- The current waveform distortion(such as third harmonic) caused by nonlinear load can be isolated without affecting the Grid.
