The main performance and technical indicators

This power of the power grid is a measure of the 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.
