By using a special transformer, WEG was also able to connect 12-pulse variable speed drives, resulting in less harmonic interference
and thus higher energy efficiency.
I would say power failure caused by harmonic interference
and then it can't propel straight or navigate and it hit rocks," said Mr Latarche.
The screw compressor uses a low harmonic, ABB industrial drive, which minimizes harmonic interference
on the mains supply and avoids the use of complex solutions to ensure conformity with G5/4 requirements.
