But Derek’s question still remains to be answered. Isn’t there a normative annex with this kind of background info? Ken Javor Phone: (256) 650-5261

However now that it is in the standard(s). It will be hard to get it removed. It is the problem for all of us, not having time to attend all of the different committees and putting our two cents worth into the standard writing. That's why I have personally have started becoming active in the standards committees, although on a limited basis (eg as time permits).

I believe the measurement is to be performed with the LISN and EMI filters in place.

I would have kept it simple and asked for an ampl-freq response check, because I think that accomplishes the same thing. _______________________________________ _____________________________________________ Ralph McDiarmid | Schneider Electric | Renewable Energies Business | CANADA | Regulatory Engineer From: Derek Walton <[email protected]> To: [email protected] Date: 04/18/2011 01:03 PM Subject: [PSES] LISN Phase angle ________________________________ Hi All, I understand that it is now important we measure LISN phase as well as impedance. Can anyone point me to the document requiring that please.
