Myth Posts: 1 Rating: (0)	Hi, My customer is claiming that our Micromaster and Sinamics is generating a lot of harmonics. They are questioning me how much is my current and voltage harmonics distortion. I ask them to use line reactor but they are asking me to provide a graph to prove on the harmonics reduction. Rg, Myth

You will find it here, hoping that the information you findthere ishelpful: /tf/WW/en/Posts/31513 Basically, it is stated there that: A line reactor will help with low-frequency harmonics generated by the drive, but high-frequency harmonics must be dealt with through proper installation and grounding of the drive. Hope this helps, Daniel Chartier
