Re: [PSES] Power line noise expert?

Thanks everyone, I believe I’ve found the right person to help. I believe the question was all about monitoring/understanding power distribution systems in large buildings. Cheers, Ken ___ I'm here to help you succeed! Feel free to call or email with any questions related

Re: [PSES] Conducted emission - AC line filters makes it worse

It's three phase -- and you'll need a three-phase filter sharing one return winding rather than three single phase filters. IMHO. Cortland Richmond -Original Message- >From: Amund Westin >Sent: Jun 28, 2020 4:58 AM >To: EMC-PSTC@LISTSERV.IEEE.ORG >Subject: [PSES] Conducted emission

Re: [PSES] Conducted emission - AC line filters makes it worse

Hi Amund This sounds like a very interesting problem. Likely many people will have advice. Maybe get lucky and someone will have had this exact same problem. I'd like to help if I can. Do you have more information on the failure? What test standard and test method did you use? How much over

[PSES] Conducted emission - AC line filters makes it worse

A 3-phase product has three internal AC driven devices. The product fails on Conducted emission. When connecting AC filters to each internal AC driven devices, the emission gets even worse. Any clue about this phenomena? Is it some kind of impedance mismatch which derate the filters
