Greg Leyh had measurements of streamer current from inside the topload
of Electrum.  There might also be base current measurements.

By the way, I stopped using the Weebly web developer [modern and easy, but not very customizable] and went back to a more manual HTML service, so all the old Electrum waveforms are available again:
