An overview,
When the power quality of the power grid is disturbed or polluted, it can not meet the relevant national standards, we must improve the power quality of the power grid. In order to understand the actual situation of power quality of power grid, it is necessary to have corresponding equipment to test and analyze it. The following is a detailed description of the specific performance, parameters and use methods of the power quality analyzer.
