Wayside Observer Posted June 13, 2020 Report Share Posted June 13, 2020 On the off chance anybody’s interested, here are a couple of pictures of the FPT PCC car measurements demo I did on the bench since access to the real thing for a 1:1 scale real live example is severely restricted right now. The same principles apply to TTC PCCs so nobody get into a snit about the off topic. The rig. One if these is not like the other. When resistance values get small, the four wire Kelvin setup is the way to go. Two wire measurements give bogus results. Those of you who have been reading your vintage GE and WH publications know why that’s an issue with transit equipment. A real PCC car would’ve been more fun. 5 Link to comment Share on other sites More sharing options...
