Partial discharge in VFD driven 400V motors, does it really exist?

[biggeorgetechnical]

I am wondering if any forum members can share their knowledge on this subject? There was a lot of discussion on VFD spikes/mitigation recently in thread titled "Terminator networks for VFD" Can these spikes create enough electric stress to generate ozone in a low voltage induction motor?

My answer is if the spikes are strong enough to breakdown the insulation in the windings therefore leading to arcing, yes. And the wife likes the smell of ozone....weird.
