App note from STMicroelectronics about current sensing using Rogowski coil together with STPMxx metering device. Link here (PDF)

This application note describes the benefits of a current sensing system for metering applications using STPMxx metering devices and a current sensor developed by Pulse Engineering Inc. (hereafter referred to as “Pulse current sensor”), based on the Rogowski coil principle. Following an overview of the Rogowski coil principle, the Pulse current sensor is introduced along with a comparison to other current measuring devices. This is followed by a presentation of the characteristics of the STPMxx family of metering devices, and the results of accuracy testing conducted using a demonstration board with the STPM01 and the Pulse current sensor.

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
