I’d like to present the openZmeter project http://www.openzmeter.com.
It’s a new open-source effort for smart energy metering and power quality measurement. It’s based on a professional and accurate hardware design, following international standards like EN50160 and IEC61000-4-30.
It’s main features are:
- Voltage RMS
- Current RMS
- Active, reactive and apparent power
- Power factor
- Realtime waveforms
- Harmonics up to 50th.
