eauel/openzmeteropenzmeter (oZm) is an Open Source system designed for power quality analysis and smart energy metering in power networks. It has been designed to comply with international standards IEC 61000-4-30 and EN 50160.
Rogowski is an open-source printed circuit board by eauel, from the eauel/openzmeter repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 88 × 94 mm with 17 parts on 11 nets, routed with 1,152 tracks and 752 vias.
It is built around the INA128U. Its parts include 7 capacitors, 7 resistors, 2 ICs and 1 connector.
openzmeter (oZm) is an Open Source system designed for power quality analysis and smart energy metering in power networks. It has been designed to comply with international standards IEC 61000-4-30 and EN 50160. It is able to measure RMS voltages with an accuracy up to 0.1%, frequency up to 10 mHz (between 42.5 and 57.5 Hz) and RMS currents according to different sensor probes (the basic version can handle up to 400 V and 50 A RMS using an onboard Hall effect sensor with a precision of 1%).

17 parts, built around the INA128U. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the eauel/openzmeter repository on GitHub, at the commit this page was made from: the board is Hardware/Rogowski/Rogowski.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
