I'm researching a home power meter project, and despite all that I've read on Open Energy Monitor [http://openenergymonitor.org/emon/] and a nice if difficult-to-read Instructable [http://www.instructables.com/id/Make-a-Rogowski-coil/], I haven't seen anybody put Rogowski coils forward as a viable alternative to other current sensors. For my version of the power meter, I'm planning on using the Analog Devices ADE7753, which has the integrator on the current input that would be necessary to get the correct value from the Rogowski coil, perhaps it's that folks are looking to use a simpler (if ultimately more expensive) way to measure current directly with an Arduino.
So, the question is: is anybody else using Rogowski coils for current sensing? Are they DIY or purchased? Opinions about accuracy, efficacy, etc.?
