Tips: Characteristics of ATO 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.
High efficiency 30kVA solation transformer is dry type air self cooling one, which is available in the circuit of AC 50Hz/60Hz and convert 3 phase voltage 480V to 415V, step up 415V to 480V is optional, low cost and manufactured direct sale.
