Hi, just a nit pick. In the EESeals the silicone doesn't have a conductive property. Inside the silicone is a phosphor bronze mesh where the parts connected to each pin get their ground. The mesh sticks out of the silicone at the edges as whiskers, they engage the connector shell. That shell as you point out must have a good bond to the case. I've used these successfully for more than 20 years, the only downside is the price. Thanks for posting these great videos.
Hi, I wonder what setup would you use for monitoring the EMI frequencies between DC and 30 MHz. present in a 240V electrical installation: Can you please comment on that?
Hi Torito, check this probe, th-cam.com/video/RrVsoWCMyH0/w-d-xo.htmlsi=Z_19B5qMecjSPVSf. But bear in mind, the senstivity is not as good as other RF current probes, so you may miss small signals. So perhaps just a good quality Hall effect current probe is better.
@@MachOneDesignEMC Thank you, I watched the video but I'd like to use a spectrum analyzer to see the frequency domain and then somehow filter out the dirty electricity. I know you are running a business and I'm sure i can't afford your services but pease help me out with some free advice. I suffer from EHS and I'm trying to get rid of the dirty electricity from my electrical installation. God bless you Sir
I wonder if that company has that technology patented. Seems like it would be pretty easy to replicate those seals. Even if the seal itself couldn't be copied I think it would be easy to add a small pass through adapter pcb that grounds to the connector metal.
In the past, I have crammed a couple of 10nF capacitors into a 9-pin D connector housing, wasn't particularly fiddly - but I guess the point of the seal is that is quick and easy to install...

Nigel, many thanks indeed for the corrections. Well explained. I also agree with you on the price point. :)
a super idea.
Do you have an online course to learn all of these fundamentals knowledge for emc?
Hi, making one at the moment, and I will let you know once it is ready.

@@Torito1774 try Onfilter, they have some good filters that can clean the noise in your installation. www.onfilter.com

It has been around in various forms since 1970s.
