I know this is a general Mechanical Engineering forum, but there is no Hydraulic forum and this is the nearest trade. https://www.youtube.com/watch?v=47Dx6TvuJTc I've been doing a project on electrostatic discharge, and the company I work for (I won't mention the name as I'm not here advertising for it) has done a lot of research into prevention and causes of electrostatic discharge. I had a customer come in from JCB a few days ago however and I was doing some unrelated tests, and mentioned it and he hadn't even heard of it and was amazed!! So I was wondering how much of electrostatic discharge have people heard of? Is this something that people have come across?? I've uploaded and interesting video that we have done at my company if you're interested (see above). If people are interested then I can upload more information regarding the subject.
