Re: [802.3_4PPOE] PD Transients (yseboodt_04)

Hi Lennart,
The new text:  "referenced from when the ‘final voltage’ is reached at the source", sets a time boundary which is after the time that the PD starts to violate Ppeak_PD.  Seems like it should start at the beginning of the transient, so that the PD Peak excursions that are beyond Ppeak_PD are no wider than 10ms and 6ms, to match Tlim_min in the PSE section.
Best Regards,

Hi folks,

Attached proposed baseline for the PD transients section.
At the September meeting it became obvious that Table 145-30 wasn't terribly clear.

I've re-simulated all of the transient conditions and, except for Class 7, everything is OK. We may want to consider increasing the ILIM for Class 3, Class 4, and Class 8 to make it such that PD's that "intrinsically" should be fine actually are.
See simulation_annot.pdf for simulation results.

Kind regards,
