The main performance and technical indicators
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:
