The openZmeter three-phase (oZm3) is our new improved oZm for three-phase networks. Ready for home or industrial installations. It can measure up to 320 VAC or 440VDC line voltages. Current measurements depend on selected current probes (Rogowski, current transformer, etc). See datasheet for details.

Description
openZmeter (oZm) is an opensource system aimed to help people to analyze and visualize power quality and electric energy in power networks. It has been designed to comply with international standards such as IEC 61000-4-30 and EN 50160 with a very reduced form factor.
It has been designed to comply with international standards such IEC 61000-4-30 and EN 50160. It can measure single or three-phase systems (85 to 320VAC) with an accuracy of up to 0.1%. DC systems and nominal frequencies of 50 and 60Hz are also supported and can be measured with resolutions up to 10 mHz. Different current probes can be used (current transformer, Hall effect, Rogowski and others) as long as they comply with the allowed input voltage levels.
