NADXC power harmonic measuring tester
Also called name
NADXC Power Harmonic Meter, Power Harmonic Alarm, Power Harmonic Tester, Power Harmonic Analyzer, Power Harmonic Measurement Analyzer

The main performance and technical indicators of NADXC
This power quality of the power grid is a measure of the quality of the power supplied to the user at the receiving end and for the user to use. It covers five aspects: supply voltage tolerance, utility harmonic, three-phase voltage unbalance, power system frequency tolerance, voltage fluctuation and flicker.
NADXB power harmonic measurement alarm object for the 45 ~ 65Hz AC frequency measurement of the signal.

The specific technical parameters are as follows
