Thanks Gus for replying to my post and yes I could write a book on shaft current bearing failures. The company I work for is a little cautious about airing it's problems but I will try and be diplomatic. The magnitude of the problem caught everyone off guard and we have been playing...
If you have shaft currents caused by a convertor and are installing two insulated bearings is it considered all right to put grounding brushes on both ends of the shaft. We seem to have different views on this subject in our company, my opinion is that the current wants to seek it's own source...
