Is it possible to install 690V softstarter on a 3.3kv 400kw motor for wood chipper application. For VFD, we used to install a step down transformer at the input of VFD, then at the output there was a sine wave filter and a step up tranformer afterwards. Is it possible to do the same way for a softstarter? Has anyone of you done this before?

Yes, you can use a step down transformer and a step up transformer. You do not need the sinewave filter, but why not just use a standard MV soft starter. I am sure it would be cheaper!!
